Operating instructions
DC current measurements
1. Set the slide switch to 40 A DC or 400 A DC
2. Connect the negative output of the Current Clamp TP-CC400
(black) to the negative side of the input of the measuring in-
strument. Connect the positive output of the Current Clamp
TP-CC400 (red) to the positive side of the input of the mea-
suring instrument.
3. Switch the measuring instrument on and set it to 200 mV
DC, 400 mV DC or 2 V DC full scale input range.
4. With firmly closed jaw, press the zero button until the in-
struments reads zero.
5. Open the jaw and fully enclose the current-carrying conduc-
tor(s) and close the jaw again, no air gap is allowed between
the two halves. The output voltage is positive when the cur-
rent flows from the underside to the upside of the clamp.
6. Read the measured voltage value and convert it to the corre-
sponding current value:
40 A range: 10 mV equals 1 A
400 A range: 10 mV equals 10 A.
AC current measurements
1. Set the slide switch to 40 A AC or 400 A AC
2. Connect the negative output of the Current Clamp TP-CC400
(black) to the negative side of the input of the measuring in-
strument. Connect the positive output of the Current Clamp
TP-CC400 (red) to the positive side of the input of the mea-
suring instrument.
3. Switch the measuring instrument on and set it to 200 mV
AC, 400 mV AC or 2 V AC full scale input range.
4. Open the jaw and fully enclose the current-carrying conduc-
tor(s) and close the jaw again, no air gap is allowed between
the two halves.
5. Read the measured voltage value and convert it to the corre-
sponding current value:
40 A range: 10 mV equals 1 A
400 A range: 10 mV equals 10 A.
