  Read this manual carefully before using the instrument. Failure to use the instrument in accordance with the manufacturer’s specifications can affect the protection which it provides.

• WARNING
  Sources of danger include e.g. mechanical parts, which can cause serious injuries. Objects are also at risk (e.g. damage to the instrument).

• WARNING
  An electric shock can result in death or serious injury and jeopardise the function of objects (e.g. damage to the instrument).

• WARNING
  Unauthorised modification and/or changes to the instrument are not permitted for reasons of safety and approval (CE). In order to ensure safe and reliable operation of the instrument, you must always comply with the safety information, warnings and the information contained in the section “Intended use”.

• WARNING
  Observe the following information before using the instrument:

  • Avoid operating the instrument near to electric welding equipment, induction heaters or other electromagnetic fields.
  • To stabilise the instrument after abrupt changes in temperature, the instrument must be allowed to adjust to the new ambient temperature for approx. 30 minutes before using it.
  • Temperatures below 5 °C can impair the readiness of the voltage tester. Please provide sufficient power supply by using suitable batteries which are also specified for the appointed temperature range!
  • Do not expose the instrument to high temperatures for a long period of time.
  • Avoid dusty and humid environments.
  • The voltage tester and accessories are not toys and must be kept out of the reach of children!
  • When working in commercial facilities, comply at all times with the accident prevention regulations for electrical systems and equipment as established by the employer’s liability insurance association.

• Please observe the five safety rules:

1. Disconnect
2. Secure the instrument against reactivation
3. Ensure isolation from the power supply (check that there is no voltage on both poles)
4. Earth and short-circuit
5. Cover adjacent live parts

• WARNING
  • Compared to the reference value of 100 k, a voltage tester with relatively low impedance does not indicate all interference voltages with an original value above the ELV. Given contact with the parts of the system to be tested, discharge can mean that the voltage tester temporarily diminishes the interference voltages to a level under the ELV. Removing the voltage tester returns the interference voltage to its original value.
  • Compared to the reference value of 100 k, a voltage tester with relatively high internal impedance at the existing interference voltage cannot clearly indicate “operating voltage not present”.
  •  If the indication “Voltage present” does not appear, we strongly recommend that you insert the earthing device before starting the work.
  • If the indication “Voltage present” appears for a part that is considered to be separate from the system, we strongly recommend that you take additional action (e.g.: use a suitable voltage tester, visually check the separating point in the electrical network etc.), verify and determine the condition of the “Operating voltage not present” of the part of the system to be tested and determine that the voltage indicated by the voltage tester is an interference voltage.

Operating

Thank you very much for purchasing the Testboy® TB 60, an automotive voltage tester with LCD display. Voltage (1 V to 60 V), polarity and continuity tests can be carried out without having to remove individual components from the battery and re-attach them. Frequency measurements of the ignition pulses can be carried out. It can also be calculated whether the engine speeds shown are correct.

Safety information

• You have chosen an instrument providing a high degree of safety. To ensure safe and correct application, it is necessary to fully read this operating manual before using the instrument for the first time.
• For test and safety purposes, the instrument has a short-circuit protective device which allows the earthing connection to be examined without any voltage drop test. The short-circuit system has a restorable fuse thus preventing the technician from destroying the fuses during the test.
• The test leads are long enough for the whole system to be tested without the need to have to regularly find an earthing point.
• The presence of voltage could result in a spark flying given contact with the earthing. That is why work should never be undertaken with a 110/220 mains voltage. The instrument is solely designed for a 12-24 volt supply.
  • On the circuit-breaker being triggered, do not touch the measurement probe or the measurement probe adapter. The measurement probe and adapter become vey hot when the circuit-breaker is triggered!
  • When applying current to components, only press the switch before the measurement probe touches the component. In this case the arc forms between the probe and the component rather than the switch. This may extend the service life of the switch.
• The following safety precautions apply:
  • Make sure that the test line and instrument are fully serviceable. Check the instrument on a known source of voltage.
  • If the display fails to indicate one or more functions in the process, do not continue to use the instrument. It must be checked by a specialist.
  • Only hold the instrument on the handles below the mechanical mark; avoid contact with the test probes!
  • The instrument must not be operated in a humid environment!
  • Always keep the instrument dry and clean. Only use a moist cloth to clean the housing.

Legend for the instrument

1. Test probe (extension)
2. LCD display
3. Mode select button
4. Polarity switch
5. Test lead
6. Earth lead
7. Black lead for power supply (-)
8. Red lead for power supply (+)
9. Light

Function

• To switch on the instrument, connect the red test lead with the plus pole of the vehicle battery and the black test lead to the minus
  pole of the vehicle battery. If necessary, connect the earth lead with a corresponding measuring point.

• The instrument has 4 modi which can be run through by pressing the “Mode select” key. For this, press the button for approximately
  one second.The instrument always starts in the first mode (voltage tester).

• Attaching or detaching the test probe adapter makes it easier to undertake testing at plugs or connectors.

Voltage test
Do not under any circumstances change the polarity in this mode!
When placing the test probes on a DC voltage within the rated voltage range, the voltage is indicated in volts on the display. If the positive pole is touched, the red LED lights up. If the negative pole is touched, the green LED lights up.

Self-test

• To see if the instrument functions properly, the following self-test can be carried out:

• In this connection, the test probe must not be touched!

  • The red LED should light up when the polarity change switch is pressed forward and with the test probe not touching anywhere
  • The green LED should light up when the polarity change switch is pressed to the rear and with the test probe not touching
    anywhere

• If these functions do not work, then the instrument should be sent in for examination by specialist personnel!

Polarity test
The red LED lights up when the test probes rest on a positive contact within the rated voltage range. The green LED lights up on the test probe coming into contact with a negative pole. The lead is considered to be interrupted should no LED light up in one of the above instances.

Continuity testing
The earth lead has to be used for this test!
By using the test probe, which supports the earth lead, you can test the conductivity between wires or components which have been disconnected from the vehicle’s electrical system. The green LED should light up when current flows between wires.

Component test

By deploying the measurement probe and earth lead, the user can activate the components to be tested without attaching them to the vehicle’s electrical system. Light, fan and fuel pumps, for instance, can be tested with this function. For this, please follow the following procedure:

1. Connect the earth lead to the negative pole of the component.
2. Connect the measurement probe to the positive pole of the component. The fact of the green LED lighting up means that the component is conductive.
3. When the green LED lights up, press the polarity switch forward and then release it immediately. You can continue with the test when the LED changes from green to red. However, the fact of the green LED going out and the red LED not lighting up or the circuit breaker being triggered means that the tester is overloaded. This could be due to the following:
   •  The component either has a short-circuit or was attached with the polarity reversed.
   • The component is a high-efficiency component.
4. The circuit-breaker regenerates itself within 60 seconds from being triggered.

Component activation solely with positive pole

• Components being tested by the user can be supplied through the TB 60 with exclusively positive voltage.
  1. Connect the measurement probe to the positive pole of the component. The fact of the green LED lighting up means that the component is conductive.
  2. When the green LED lights up, press the polarity switch forwards and then release it immediately. However, the fact of the green LED going out and the red LED not lighting up or the circuit breaker being triggered means that the tester is overloaded. This could be due to the following:
  • The component either has a short-circuit or was attached with the polarity reversed.
  • The component is a high-efficiency component.
• The circuit-breaker regenerates itself within 60 seconds from being triggered.

Component activation solely with negative pole

• Components being tested by the user can be supplied through the TB 60 with exclusively negative voltage.
  1. Connect the measurement probe to the negative pole of the component. The fact of the red LED lighting up means that the component is conductive.
  2. When the red LED lights up, press the polarity switch to the rear and then release it immediately. However, the fact of the red LED going out and the green LED not lighting up or the circuit breaker being triggered means that the tester is overloaded. This could be due to the following:
  • The component either has a short-circuit or was attached with the polarity reversed.
  • The component is a high-efficiency component.
• The circuit-breaker regenerates itself within 60 seconds from being triggered.

Trailer light test
The following procedure must be followed when examining the light system of a trailer:

1. Connect the earth lead to the earthing of the trailer.
2. By using the measurement probe, a connection can now be set up to the lighting system at the trailer plug connector. The light can be tested by now pressing the polarity change-over switch forwards.
3. The green LED lights up when the probe comes into contact with the negative pole.

Localising any missing ignition pulses
Select the “kV” mode with the Mode select button to check which ignition pulse is absent.By positioning the test probe of the tester next to an ignition cable (NO direct contact!), a capacitive coupling enables the tester to record the high-voltage ignition pulses and simultaneously display a voltage value. Any missing cylinder can be localized by monitoring each ignition cable in this way.

Measuring the frequency of the high-voltage ignition pulses

• Select the “Hc” mode with the Mode select button to change to the frequency mode.The tester can measure the frequency of the ignition pulses. By positioning the test probe next to an ignition wire (NO direct testing), a capacitive coupling enables the tester to record the ignition pulses and simultaneously display a frequency value.

• Measuring technique 1: for each cylinder at the ignition cable

• Measuring technique 2: ignition cable section of several cylinders

• Measuring technique 3: at the ignition distributor / ignition coil

• High-voltage cable between distributor and ignition coil. Move the recording head – as shown – to a point near the high-voltage cable
  connecting the distributor to the ignition coil or to where all high-voltage cables of the cylinders are found together.

• Multi-cylinder petrol engines without distributor. Move the detecting head near to a point where the high-voltage wire of each cylinder is bundled. No measurement is possible if not all the high-voltage wires are bundled. This is because of the differences in how
  far apart the recording head is from each high-voltage wire.

Specifications

• Engine types:
  • Petrol engines
  • 2 stroke (1 – 4 cylinders)
  • 4 stroke (1, 2, 3, 4, 5, 6, 8, 12 cylinders)
• Detection technique: detecting ignition spark noise
• Item to be detected: high-voltage cable or ignition cable

Calculation of the engine speed

• The engine speed can be calculated on the basis of the measured frequency. The calculation formula is as follows: n = 60 x f x 1 / PR
• “n” stands for the engine speed
• “f” stands for the frequency of the high-voltage ignition pulse.
• “PR” stands for the ratio coefficients between “f” and “n”.
• The PR value can be ascertained on the basis of the following engine table:
  PR| 4-stroke| 2-stroke
  ---|---|---
  1/2| 1 cylinder|
  1| 2 cylinders| 1 cylinder
  3/2| 3 cylinders|
  2| 4 cylinders| 2 cylinders
  5/2| 5 cylinders|
  3| 6 cylinders| 3 cylinders
  4| 8 cylinders| 4 cylinders
  6| 12 cylinders|

Peak detection
The voltage peak can be checked in this mode. Use the mode select button to change to the “+/-” mode and set the maximum permitted voltage by pressing the mode select button. The possible settings are 0.5 V, 1 V, 2 V, 5 V, 10 V and 48 V. With the required target value set, apply electrical current to the corresponding lead with the test probe. The instrument emits an acoustic signal when the set value is exceeded. A change is then made to the next higher setting and no further sounds should come from the instrument.
Example: A 12 V maximum is to be applied to the lead. The instrument is set to 10 V and checked. As the 10 V have been exceeded, a sound is heard from the instrument. The next higher range is now chosen (48 V) and the signal is silenced.

Cleaning
Use a damp cloth and mild household detergent to clean the instrument should it become soiled through daily use. Never use aggressive cleaning agents or solvents to clean the instrument.
To avoid electric shocks, do not allow moisture to penetrate the housing.

Maintenance
The instrument does not require special maintenance when used as specified in this operating manual.
