All equipment subject to this directive is marked with this logo.

Disposal of used batteries
As an end user, you are legally obliged (battery law) to return all used batteries; disposal in the domestic waste is prohibited!
Batteries containing contaminant material are marked with this symbol indicating that they may not be disposed of in the domestic waste.
The abbreviations used for the crucial heavy metals are:
Cd = cadmium, Hg = mercury, Pb = lead.
You can return your used batteries free of charge to municipal collection points or anywhere where batteries are sold!

Operation

Thank you for purchasing the Testboy® TV 217. The Testboy® TV 217 is intended for measuring systems of Category CAT III and for voltages that do not exceed 600 V (AC or DC) in an earthed state.

Before taking a measurement, allow the instrument to acclimatize.

• The user must comply with all the usual safety regulations when using this clamp meter.
• The instrument can indicate gross errors if it is used in the vicinity of appliances that cause interference or noise.
• Only use the instrument as described in this manual; failure to do so could impair its protective equipment.
• Only use the instrument if the housing and clamp jaws are in a faultless condition.
• To prevent damage to the instrument, do not exceed the maximum input values specified in the technical data.
• Pay attention to the function selection switch and make sure that it is set to the correct position before each measurement.
• Exercise especial caution when performing tasks on naked conductors or busbars (wear protective clothing if necessary).
• Any inadvertent contact with the conductor can result in an electric shock.
• Exercise caution when working with voltages greater than 60 V DC or 30 V AC RMS. Such voltages pose a danger of an electric shock.
• The clamp must first be removed from the circuit to be tested before switching to other functions.
• Ensure that your fingers are behind the safety ring during measurement.
• To avoid incorrect measured values: Change the batteries when the symbol appears.
• Ensure that the test instrument is in faultless condition before each measurement. Test the function using a known, functioning power source before using the instrument.
• Always discharge the capacitances and disconnect the instrument to be tested from the power supply before performing diode, resistance or continuity measurements.
• Insecure connections with the installed electrical contacts mean that voltage tests performed on sockets can pose problems and produce misleading results. Additional measures should therefore be taken to ensure that the lines are not live.
• Exercise caution when working in the vicinity of exposed accessible conductors or busbars. Use personal protective equipment.
• Do not use a current measuring sensor with visible wear on the clamp.

Product-specific safety information

• Always disconnect the instrument from the power supply and neutralize your own static charge before opening the instrument, otherwise you could damage the internal components.
• All adjustment, maintenance and repair tasks performed on an energized clamp meter may only be performed by qualified specialist personnel familiar with the specifications of this manual.
• “Qualified personnel” refers to persons familiar with the installation, design and operation of the equipment and the associated dangers. They are sufficiently experienced and authorized to connect or disconnect electrical circuits and installations in accordance with professional standards.
• When the instrument is open, remember that some internal capacitors may retain lethal voltage potential after being switched off.
• If faults or irregularities occur, decommission the instrument and make sure that it can no longer be used until after it has been checked.
• If the instrument is not used for an extended period, remove the batteries and keep the instrument in an environment that is not moist or too hot.
• Exercise extreme caution when performing tasks on uninsulated conductors and busbars. Contact with these components could result in an electric shock! Use the appropriate protective equipment!

Definition of the measurement categories

• Measurement category II: Measurements on circuits directly connected to a low voltage system electrically via a plug. Typical short-circuit current < 10 kA
• Measurement category III: Measurements within the building installation (stationary consumers with a non-plug-in connection, distributor connection, permanently installed instruments in the distributor). Typical short-circuit current < 50 kA
• Measurement category IV: Measurements at the source of the low voltage installation (meters, mains connection, primary overcurrent protection). Typical short-circuit current >> 50 kA
• To establish the measurement category with a combination of test lead and measuring instrument, the lowest category – of either the test lead or the measuring instrument – applies.
• The user must comply with all the usual safety regulations when using this clamp meter:
  • Protect against dangers from electricity.
  • Protect the measuring instrument against misuse.
• For your own safety, use only the measuring heads included in the scope of delivery of the instrument. Check that the instrument is in a faultless condition before use.

Maintenance and cleaning
Clean the housing with a dry cloth (no cleaning agents) at regular intervals. Do not use any abrasive or scouring agents, or solvents.

To avoid electric shocks, do not allow moisture to penetrate the housing.

Replacing the battery
Before removing the rear panel, switch off the clamp meter and remove the test leads so as to avoid electric shocks.

Procedure:

• If the operating voltage of the battery is insufficient, the symbol will appear on the LCD display; the battery must then be replaced.
• Set the band switch to OFF.
• Unscrew the safety screw at the rear with a screwdriver. Remove the used batteries and replace with two new type 1.5 V AAA batteries.
• Replace the cover and secure with the screw.
  Do not dispose of the batteries in the domestic waste. There will be a collection point near you!

OPERATING MANUAL

If the set value is exceeded for an extended period by the current being measured, heating can occur that can impair the operating and functional safety of internal circuits.
To prevent discharges and/or incorrect measured values, do not perform current measurements on high-voltage cables (> 600 V).

• AC current measurement
  • Make sure that the test leads are disconnected from the measurement sockets.
  • Set the function switch to band A~. Ensure that you have selected a suitable measurement range. Clasp one of the conductors to be measured with the clamp jaw from the current transformer. Make sure that the clamp is fully closed.
  • Read off the measured value.
• AC/DC voltage measurement
  • The maximum input voltage in the V AC/DC range is 600 V AC/DC. To prevent dangers from electric shocks and/or damage to the instrument, never perform measurements of voltages over 600 V AC/DC.
  • Set the function switch to the “V” band.
  • Press the “FUNC” button to select AC/DC.
  • Insert the black and red test leads into the COM or INPUT inputs.
  • Apply the test leads to the circuit to be measured and read off the value.
• Resistance/continuity/diode measurement
  • Before carrying out a resistance measurement, make sure that the circuit to be measured is not live and that all capacitors have been discharged.
  • Set the function switch to the “Ω/ ” band.
  • Press the “FUNC” button to switch between measuring the resistance, continuity and diode. Insert the black and red test leads into the COM or INPUT inputs.
  • Apply the test leads to the circuit to be measured and read off the value.
  • Please note: The continuity test is used to locate short circuits or open circuits.
• Capacitance measurement
  • Set the function switch to the ” ” band.
  • Insert the black and red test leads into the COM or INPUT inputs.
  • Apply the test leads to the circuit to be measured and read off the value.
• Temperature measurement
  • Set the function switch to the “TEMP” band.
  • Plug the temperature sensor into inputs COM or INPUT.
  • Apply the sensor to the element to be measured and read off the value.
• Auto power-OFF
  • The instrument automatically switches off after approx. 30 minutes to save the battery.
  • If the instrument is in “sleep mode”, it can be returned to normal measuring mode by pressing the “FUNC” button.
