P 4300:
1. Insert black banana plug into the COM-jack and the red banana
plug into the V-Ω jack of any multimeter with a minimum input
impedance of 1 MΩ.
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 is directly in amperes.
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.
Application notes
1. In the case of DC current, the output is positive when the
current flows from the upside (marking "+" textured on the jaws)
to the underside of the clamp. The red banana plug is positive.
2. In the case of DC current measurement, a hysteresis effect can
occur so that it is impossible to zero the clamp properly. To
eliminate this effect, open and close the jaws several times and
push zero adjustment button.
