  • Before using the meter inspect the case. Do not use the meter if it is damaged or the case (or part of the case) is removed. If you can identify cracks or missing parts stop using the meter immediately.
  • Inspect the test leads for damaged insulation or exposed wires. Check test leads continuity. Replace damaged test leads with leads that are suitable to the meter that meets or exceed the safety requirements.
  • Comply with local and national safety codes. Use personal protective equipment (approved rubber gloves, face protection, and flame-resistant clothes) to prevent shock and arc blast injury where hazardous live conductors are exposed.
  • Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and grounding.
  • The limit operation to the specified measurement category, voltage, or amperage ratings.
  • Use Product-approved measurement category (CAT), voltage, and amperage-rated accessories (probes, test leads, and adapters) for all measurements.
  • Use the correct terminals, function, and range for measurements.
  • Before each use, verify meter operation by measuring a known voltage first.
  • Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
  • Do not use the meter around explosive gas, vapor, or in damp or wet environments
  • The function selector should be placed in the right position before using the unit, do not change the range/function during measurement to avoid damage to the meter or equipment under test.
  • When the meter is working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken as there is a danger of electric shock.
  • Do not touch the probes to a voltage source when the test leads are connected to the current terminals.
  • Connect the common test lead before the live test lead and remove the live test lead before the common test lead.
  • Do not use a current measurement as an indication that a circuit is safe to touch. A voltage measurement is necessary to know if a circuit is hazardous.
  • Do not use the HOLD function to measure unknown potentials. When HOLD is turned on, the display does not change when a different potential is measured.
  • When using the test leads, ensure the leads are fully seated and keep your fingers behind the finger guards.

OPERATING INSTRUCTIONS

AC/DC VOLTAGE MEASUREMENT
WARNING  To avoid electric shock or damage to the meter, do not attempt to measure voltages higher than the rated voltage (AC 750V, DC 1000V).
When measuring high voltages, take extra care to avoid electric shock.
When connecting the test leads to the circuit or device, connect the common (COM) test lead before connecting the live lead; when removing the test leads, remove the live lead before removing the common test lead.
1. Connect the common test lead to the COM terminal then insert the red test lead into the VΩHz.
2. Switch the function selector to V; DC measurement is default or presses the BLUE button to switch between DC and AC measurement mode.
3. Connect the test leads across with the object being measured. The measured value shows on the display.

NOTE:

  • In each range, the meter has an input impedance of 10MΩ except the mV range which the input impedance is 3000MΩ. This loading effect can cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal to 10kΩ, the error is negligible (0.1% or less).
  • When measuring mV, you must press RANGE manually to enter the mV range.
  • When voltage measurement has been completed, disconnect the connection between the testing leads and the circuit under test, then remove the testing leads from the input terminals of the meter.

TTIDM1000VAR Auto-Ranging Multimeter - 3

AC/DC CURRENT MEASUREMENT
**
WARNING**

  • Never attempt to make an in-circuit current measurement when the open-circuit potential to earth is >600 V.
  • To prevent possible electric shock, fire or personal injury, switch off the power supply of the circuit before measuring the current and then connect the meter with the circuit in series.
  • Check the Meter’s fuse before testing.
  • Use the proper terminals, switch position, and range for your measurement.
  • Never place the probes in parallel with a circuit or component when the leads are plugged into the A (Amps) terminals.

To measure current:

  1. Connect the common test lead to the COM terminal then insert the red test lead into the µmA or 10A MAX input terminal.
  2. Set the function selector to mA or A.
  3. The meter defaults to DC current measurement mode. To toggle between DC and AC current measurement function, press the BLUE button.
  4. Connect the test lead in series to the return circuit to be tested. The measured value shows on the display.
  5. Display the effective value of the sine wave (mean value response).
  6. Press Hz% to obtain the frequency and duty cycle value.

NOTE:

  • If the value of the current to be measured is unknown, use the maximum measurement position, and reduce the range step by step until a satisfactory reading is obtained.
  • For safety purposes, each measurement time for >5A current should be less than 10 seconds and the interval time between 2 measurements should be greater than 15 minutes.
  • When the current measurement has been completed, disconnect the connection between the testing leads and the circuit under test, then remove the testing leads from the input terminals of the meter.

RESISTANCE MEASUREMENT

WARNING

  • To avoid damaging the meter or to the device under test, disconnect the circuit power and discharge all the high-voltage capacitors before measuring resistance.
  •  To avoid electric shock, do not input higher than DC 60V or AC 30V voltages.

To measure resistance, remove power from the circuit and connect the meter as followed:

  1. Connect the common test lead to the COM terminal then insert the red test lead into the VΩHz.
  2. Set the function selector to Ω, resistance measurement (Ω) is default or press the BLUE button to select Ω measurement mode.
  3. Connect the test leads across with the object being measured. If there is a lead on the resistor or SMT resistor, use the included testing adaptor to carry out testing. The measured value shows on the display.

NOTE:

  • The test leads can add 0.2Ω to 0.5Ω of error to resistance measurement. To obtain precision readings in low resistance measurement, short-circuit the input terminals beforehand, using the relative measurement function button REL to automatically subtract the value measured when the testing leads are short-circuited from the reading.
  • If Ω reading with shorted test leads is not ≤0.5Ω, check for loose test leads or other reasons.
  • For high-resistance measurement (>1MΩ), it is normal to take several seconds to obtain a stable reading. To obtain a stable reading, use the test lead as short as possible or use the included testing adaptor to carry out the measurement.
  • The LCD displays OL indicating an open circuit for the tested resistor or the resistor value is higher than the maximum range of the meter.
  • When resistance measurement has been completed, disconnect the connection between the testing leads and the circuit under test, then remove the testing leads away from the input terminals of the meter.

TTIDM1000VAR Auto-Ranging Multimeter - 5

CONTINUITY MEASUREMENT
WARNING

  • To avoid damaging the meter or to the device when testing, disconnect the circuit power and discharge all the high-voltage capacitors before testing for continuity.
  • To avoid electric shock, do not input higher than DC 60V or AC 30V

Use the continuity function as a fast, convenient method to check for opens and shorts. For maximum accuracy in making resistance measurements, use the meter’s resistance function. To test for continuity, remove power from the circuit and connect the meter as followed:

  1. Connect the common test lead to the COM terminal then insert the red test lead into the VΩHz. Set the function selector to and press the BLUE button to select measurement mode
  2. Test the continuity by connecting the conductor or circuit with test leads. If resistance is measured at <10Ω, an audible signal will sound. If the circuit is open (>35Ω), the display will show OL.

NOTE:

  • Open circuit voltage is around 0.45V
  • When continuity testing has been completed, disconnect the connection between the testing leads and the circuit under test, and remove the testing leads away from the input terminals of the meter.

DIODE MEASUREMENT
WARNING

  • To avoid possible damage to the meter and to the device under test, disconnect the circuit power and discharge all high-voltage capacitors before testing diodes.
  • To avoid electric shock, do not input higher than DC 60V or AC 30V
  1. Connect the common test lead to the COM terminal then insert the red test lead into the VΩHz.
  2. Set the function selector to and press the BLUE button to select measurement mode.
  3. For forwarding voltage drop readings on any semiconductor component, place the red test lead on the component’s anode and place the black test lead on the component’s cathode. The measured value shows on the display.

NOTE:

  • In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8V; however, the reverse voltage drop reading can vary depending on the resistance of other pathways between the probe tips.
  • The LCD will display OL indicating the diode being tested is open or polarity is reversed The unit of the diode is Volt (V), displaying the forward voltage drop readings.
  • When diode testing has been completed, disconnect the connection between the testing leads and the circuit under test, then remove the testing leads away from the input
    terminals of the meter.

CAPACITANCE MEASUREMENT
WARNING
To avoid possible damage to the meter and to the device under test, disconnect the circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the DC Voltage function to confirm that the capacitor is discharged.
To measure capacitance, connect the meter as per below:

  1. Connect the common test lead to the COM terminal then insert the red test lead into the VΩHz.

  2. Set the function selector to and press the BLUE button to select nF measurement mode.
    • At that time, the meter will display a fixed value which is the meter’s internal fixed distributed capacitance value. To ensure accuracy when measuring a small value of capacitance, the tested value must subtract this value, REL mode can help on that.

  3. Connect the test leads across with the object being measured. The measured value shows on the display.
    • For more convenience, use the included testing adaptor for measuring capacitors. Insert the capacitor to be tested into the corresponding “+” and “-” jack of the testing
    adaptor. This method is more stable and correct when testing for small values of capacitance.

NOTE:

  • It takes longer when the tested capacitor is more than 100µF
  • The LCD displays OL indicating the tested capacitor is shorted or it exceeds the maximum range.
  • When the capacitance measurement has been completed, disconnect all the connections between the testing adaptor, capacitor, and meter.

The benefits conferred by this warranty are in addition to all rights and remedies which you may be entitled to under the Australian Consumer Law, and any other statutory rights you may have under other applicable laws. This warranty does not exclude, restrict or modify any such rights or remedies.
Warranty exclusions
This express warranty does not apply where a defect or other issue with the product is caused by normal wear and tear, misuse or abuse of the product.
Consumer guarantees
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and for compensation for any other reasonably foreseeable loss or damage.
You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.

Any cost incurred by you in bringing the product to the place of purchase will be borne by you.
To make a claim under this warranty, the product and proof of purchase must be returned to the Total Tools place of purchase during the warranty period specified above.
If your warranty claim is accepted, we (or the Total Tools store that handles the claim on our behalf) will, at our discretion, repair or replace the product, or refund money to you and take back the product.
