Operation
NOTES: Read and understand all Warning and Caution statements in this operation manual prior to
using this meter. Set the function select switch to the OFF position when the meter is not in use.
AC True RMS Current Measurements
WARNING: Ensure that the test leads are disconnected from the meter before making current
clamp measurements.
1. Set the Function switch to the A position.
2. Select the fundamental frequency (50Hz or 60Hz) with the 50Hz-60Hz push-button. The LCD
display will reflect the selected frequency.
3. Open the clamp loop by pressing the latch tabs and
disconnecting the clamp coupling connector.
4. Fully enclose only one conductor centered inside the clamp
loop. Allow at least 25mm between the conductor and the
clamp coupling connector.
5. The meter’s LCD will display the current (A) and frequency
(Hz) readings.
Note: For measurements lower than 3A, the meter’s frequency
display will indicate ‘0’.
‘OL’ is displayed when the measurement exceeds the
specified maximum limit.
AC True RMS Voltage Measurements
WARNING: Maximum input is 600Vac rms. Do not attempt to take any voltage measurement that
exceeds this limit. Exceeding the limit could cause electrical shock and damage to the meter.
1. Insert the black test lead into the negative COM terminal and the red test lead into the positive
V terminal.
2. Set the function switch to the V position.
3. Select the fundamental frequency (50Hz or 60Hz) with the
50Hz-60Hz push-button. The LCD display will reflect the
selected frequency.
4. Connect the test leads in parallel to the circuit under test.
5. Read the voltage measurement (V) and frequency (Hz) on
the LCD display. ‘OL’ is displayed when the measurement
exceeds the specified maximum limit.
Note: For measurements lower than 30V, the meter’s
frequency display will indicate ‘0’.
