5. Connect test leads in series with the circuit to be measured.
6. Read the reading on the display. For DC current measurement, the polarity of the red test lead connection
will be indicated as well.
Note:
When the display shows the overrange symbol „OL", a higher range has to be selected.
Measuring Current (with clamp, optional)
1. If you want to measure DC current, you must use the DC clamp. If you want to measure AC current, you
must use the AC clamp.
2. Connect the negative (-) output lead of the selected clamp to the „COM" jack, connect the positive ( + )
output lead of the clamp to the „INPUT" jack,
3. Set the range switch to position
4. Select DC current measurement or AC current measurement with the „FUNC. " button.
5. Select auto range or manual range with the „RANGE" button.
In manual range, if the the current magnitude to be measured is not known beforehand, select the highest
range.
6. Clamp the circuit to be measured with the clamp.
Each time only one cable should be clamped and the cable hould be in the center of the clamp jaws.
7. Read the reading on the display. For DC current measurement, the polarity of the positive ( + ) output lead
of the clamp will be indicated as well.
Note:
1. In manual range mode, when the display shows the overrange
symbol „OL", a higher range has to be selected.
2. Don't touch the circuit under test with hand or skin.
3. Matching problem about the meter and the sensitivity of the clamp :
a. The sensitivity of the matching clamp is 0.1A/0.1mV. If you use a matching clamp, the present indicated
value is same to the measured value.
b. If you use a clamp whose sensitivity does not equal 0.1A/0.1mV, you should multiply the present reading by
a factor which is determined by the used clamp, the result is the measured value.
To determine the factor, plese refer to the instruction of the clamp which you use.
Measuring Resistance
1. Connect the black test lead to the „COM" jack and the red test lead to the „INPUT" jack (Note: The polarity of
the red test lead is positive „+" ).
2. Set the range switch to range Ω.
3. Select auto range or manual range with the „RANGE" button. In manual range mode, when the display
shows the overrange symbol „OL", a higher range has to be selected.
4. Connect the test leads across the load to be measured.
5. Read the reading on the display.
Note:
1. For resistance measurements > 1MΩ , the meter may take a few seconds to stabilize reading. This is normal
for high-resistance measurement.
2. When the input is not connected, i.e. at open circuit, the symbol „OL" will be displayed as an overrange
indicator.
