6. How to make measurements

Before making any measurements read safety precautions. Always examine the instrument and accessories used with the instrument for damage, contamination (excessive dirt, grease, etc) and defects. Examine the test leads for cracked or frayed insulation and make sure the lead plugs fit snugly into the instrument terminals. If any abnormal conditions exist, do not attempt to make any measurements.

6.1. Voltage measurements

1. Turn off power to the device under test and discharge all capacitors.
2. Select mV or V-function with the rotary function-switch.

3. Select the desired AC voltage range or DC voltage range, by pressing MODE-button.

4. Plug the black test lead into the COM input jack on the meter and connect the test lead tip to a grounded point (the reference point for measurement of voltage).

WARNING! To avoid possible electric shock, instrument damage and/or equipment damage, do not attempt to take any voltage measurements if the voltage is above 1000 V AC/DC are the maximum voltages that this instrument is designed to measure. The “COM” terminal potential should not exceed 1000 V measured to ground.

1. Plug the red test lead into the V/Ω/CAP/ /Hz - input jack on the meter and connect the circuit where a voltage measurement is required. Voltage is always measured in parallel across a test point. Turn on power the circuit/device to be measured and make the voltage measurement reduce the range setting if set too high until a satisfactory reading is obtained.

2. After completing the measurement, turn off power to the circuit/device under test, discharge all capacitors and disconnect the meter test leads.

6.2. Current Measurements

WARNING! This clamp is designed to take current measurements on circuits with a maximum voltage difference of 1000 V AC/DC between any conductor and ground potential. Using the clamp for current measurements on circuits above this voltage may cause electric shock, instrument damage and/or damage to the equipment under test. Before measuring current make certain that the test leads are removed from the instrument.

The clamp is overload protected up to 1000 V AC/DC for up to 1 Min. Do not take current readings on circuits where the maximum current potential is not known. Do not exceed the maximum current that this instrument is designed to measure.

1. Set Function Switch to 400 A / 1500 A.
2. Press the trigger to open the transformer jaws and clamp them around a conductor. Jaws should be completely closed before taking a reading.
3. Select the desired AC or DC range by pressing MODE-button.
4. DCA Zero: The zero feature removes offset values and improves the accuracy for DC current measurements.
5. Perform a zero adjustment by selecting 400A/1500A DC with the function selector switch and without a conductor in the clamp, press the ZERO button.
6. The display shows zero. The offset value is now stored and removed from all measurements
7. Now perform your current measurement, as described in points 1 – 6.

Note:

Frequency: If the measurement function 400A/1500A AC is selected, you can read in the secondary display, the frequency of the measured current value.

1. The most accurate reading will be obtained by keeping the conductor across centre of the transformer jaws. The reading will be indicated on the display.

6.3. Resistance measurements

WARNING! Attempting resistance or continuity measurements on live circuits can cause electric shock, damage to the instrument and damage to the equipment under test.

Resistance measurements must be made on de-energized (DEAD) circuits only for maximum personal safety. The electronic overload protection installed in this instrument will reduce the possibility of damage to the instrument bus not necessarily avoid all damage or shock hazard.

1. Turn off any power to the resistor to be measured. Discharge capacitors. Any voltage present during a resistance measurement will cause inaccurate readings and could damage the meter if exceeding the overload protection of 1000 V DC or AC.
2. Insert the black test leads into the COM and the red test lead into the V/Ω/CAP/→/Hz - input terminals respectively.
3. Select the desired ohm ( ) range.
4. Connect the black and red test probe tips to the circuit or device under test, making sure it is de-energized first.
5. Open circuits will be displayed as an overload OL condition.
6. Test lead resistance can interfere when measuring low resistance readings and should be subtracted from resistance measurements for accuracy. Select lowest resistance range and make the test leads short together.

The display value is the test lead resistance to be subtracted.

1. After completing measurement, disconnect the test leads.

6.4. Continuity testing

1. Set the rotary switch to the position
2. Select the ·))) function by pressing the MODE-button.
3. Follow step 2 and 4; as for resistance measurements.
