6. When 1 mV/10 mA range of clamp unit is selected, multiple the
reading displayed on the multimeter by "10" for interpreting the
measured current value in mA. For example, if the multimeter
reads 10 mV, the measured current is 10 x 10 = 100 mA.
When 1 mV/100 mA range is selected, multiple the reading
displayed on the multimeter by "100" for interpreting the
measured current value in mA. For example, if the multimeter
reads 5 mV, the measured current is 5 x 100 = 500 mA.
P 4300:
1. Insert black banana plug into the COM-jack and the red banana
plug into the V- jack of any multimeter with a minimum input
impedance of 1 M.
2. Set the power switch from "OFF" to the desired range, 200 A or
1000 A position. The green LED will light to indicate that the
clamp is switched on.
3. For current measurement below 200 amperes, set the unit to 200
A range and set the multimeter to 200 mV AC range for AC
current measurements or 200 mV DC for DC current
measurements. The reading in mV corresponds directly to A (for
example 100mV ≙ 100A).
4. For current measurements above 200 amperes, set the unit to
1000 A range and set the multimeter range to 2 V AC or DC,
depending on whether measuring AC or DC current. The reading
is now amperes x 1000.
5. When perform DC current measurement, always push the zero
adjustment button on the clamp until the multimeter reads zero.
6. Clamp the jaws around the current-carrying conductor and
interpret the reading according to step 3 or 4 above.
