OPERATING MANUAL MPI-530-IT version 1.06
Press STARTpush-button to start the measurement.
The result is displayed on the screen for 20 s.
The result can be recalled by pressing ENTER push-
button.
Measurements may be performed in the presence of interference current of a
value not exceeding 3 A rms and frequency in accordance with the value set in
MENU.
- Use N-1 clamps as signal transmitting clamps and C-3 clamps as receiving clamps. C-3 clamps
purchased with the meter must be calibrated before their first use. They may be periodically calibrat-
ed in order to prevent their ageing influence the accuracy of the measurements. Option for the cali-
bration of clamps is included in the MENU.
- If the current on measuring clamps is too low, the meter displays the following message: "Meas-
ured current is too low, measurement impossible!".
- Maximum interference current: 1 A.

Voltage at test terminals is higher than 50 V, measure-
ment is blocked.
Voltage at test terminals is higher than 24 V but lower
than 50 V, measurement is blocked.
The interfering signal (noise signal) is too high - the
measurement result may be affected by additional uncer-
tainty.
