The following operations can be performed using the keys:
WATT key
In measurement mode, you can measure active power,
apparent power, power factor and phase angle and display
the results on the LCD screen by pressing the WATT key.
MODE key
In kW measurement mode, press the MODE key to toggle
between the active power and reactive power display; In A /
V ~ measurement mode, you can toggle between displaying
the total harmonic distortion ratio Fr and the harmonic
percentage.

SET key
In the measurement mode, you can press the SET key and
then the and keys , you can adjust the current and
voltage scale and then press the SET key again to return to
normal mode. This key also serves as a confirmation key
during storage and deletion.
U key
In measurement mode, you can press this key to check the
voltage in the circuit under test and show the measured
voltage on the screen.
READ key
In HOLD mode, you can press this key to display the stored
data; press this key again to return to normal mode.
I key
In measurement mode, you can press the I key to measure
the current in the circuit under test and display the current
measured by the clamp on the LCD screen.
RS232 key
In the measurement mode, you can press the RS232 key to
transfer the current results to the PC via the specific
interface cable supplied with the clamp for the purpose of
recording / printing data and data trend graph.
Before pressing the RS232 key for transfer
data, the RS232C interface cable must be connected to the
RS232C port of the clamp and to the COM port of the PC, to
perform the communication functions.
