Warning: Please make sure that the power supply voltage matches the supply voltage before turning on the
power supply, otherwise the instrument will be burned out.
Notes: The instrument should be used under the recommended working conditions. Never use the instrument in
a place where have flammable or explosive materials, it may cause safety injuries.
3.1.2 Connecting Test Circuit
Please follow the following figure to connect the power and load, and make sure voltage and current is within
the measurement range of the instrument.
Warnings:
1. The load current flows along the thick wire in the above diagram, so these wires should have a large
enough safe load capacity.
2. The power supply of the load and the power supply of the instrument should be turned off when wiring
at the load end.
Notes:
1）When measuring large current/voltage or the current includes high frequency, it should pay attention to
possible mutual interference and noise problems when wiring.
2）The lead wire should as short as possible.
3）Use heavy gauge wire as can as possible when measuring current.
4）To reduce the distributed capacitance to ground, the wire and grounding wire should be as far away from
the instrument housing as possible.
3.1.3 Turn ON/OFF Power Supply
Turn on：Start self-check program when the instrument is enabled, the instrument will enter the measuring state
if the check result is correct.
Turn off：The upper/lower limit of current and power will be saved when the power has been turned off.
Notes ： After turning off the power, wait for 5 seconds to turn on again, otherwise the instrument may
abnormally display.
3.1.4 Power-on Measurement
Firstly, plug in the power socket on the rear panel, and use the specified voltage, the power socket should be
with a ground wire. After checking the wiring is connected rightly, turn on the instrument switch located at the
front panel, and the instrument will enter the measurement state. Apply power to the load and read out the
