UT61A, UT61B and UT61C: display effective value of sine wave (mean

value response).

UT61D and UT61E: display true rms value.

5. Press Hz% to obtain the frequency and duty cycle value.

Input Amplitude: (DC electric level is zero)

Input Amplitude: range 30%

Frequency response:UT61A and B 400Hz

UT61C , UT61D andUT61E

1kHz

Note

l If the value of current to be measured is unknown, use the maximum measurement

position, and reduce the range step by step until a satisfactory reading is obtained.

l For safety sake, each measurement time for >5A current should be less than

10 seconds and the interval time between 2 measurements should be greater

than 15 minutes.

l When current measurement has been completed, disconnect the connection

between the testing leads and the circuit under test, and remove the testing leads

away from the input terminals of the Meter.
