Operating instructions
DC current measurements
1.
Set the slide switch to 20 A DC or 80 A DC
2.
Connect the negative output of the Current Clamp TP-CC80 (black) to the
negative side of the input of the measuring instrument. Connect the positive
output of the Current Clamp TP-CC80 (red) to the positive side of the input
of the measuring 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 instruments reads
zero.
5.
Open the jaw and fully enclose the current-carrying conductor(s) and close
the jaw again, no air gap is allowed between the two halves. The output
voltage is positive when the current flows from the upside to the underside
of the clamp.
6.
Read the measured voltage value and convert it to the corresponding cur-
rent value:
20 A range: 100 mV equals 1 A
80 A range: 100 mV equals 10 A.
AC current measurements
1.
Set the slide switch to 20 A AC or 80 A AC
2.
Connect the negative output of the Current Clamp TP-CC80 (black) to the
negative side of the input of the measuring instrument. Connect the positive
output of the Current Clamp TP-CC80 (red) to the positive side of the input
of the measuring 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 conductor(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 corresponding cur-
rent value:
20 A range: 100 mV equals 1 A
80 A range: 100 mV equals 10 A.
