The screen can be automatically or manually turned off

Automatically turned off: When the current stay below 300mA for 1 minute, the screen will be turned off automatically.

After the current go higher than 300mA, it will automatically be turned on.

Manually turned off: If the screen is turned off manually, it needs to be turned on manually too. Move the yellow cursor to

Operating Method: Move the yellow cursor to the LOP, press DOWN button one more time, the yellow cursor disappears,

and then press OK button, battery energy filled/reset cycles.

Battery energy automatically add-up to be full

It corresponds the full battery energy. It should be set via the OVP.

Recommend to set it a little bit lower than the full-charged voltage value of your battery.For example, if the full-charged

voltage is 48V, it is recommend to set the OVP as 47.8V, 47.9V. When the charging voltage reaches the OVP value, the

battery energy of the meter will be automatically add up to full.

Current calibration when no load

Move the yellow cursor to the OUT, long press OK button for 3 seconds and loose. Repeat the above operation until reset to 0.

Power supply voltage

The meter can only work stably when the power supply voltage reaches 12V. If the voltage is too low, there will easy to be

slight fluctuation.

Do not use the instrument beyond the measurement range, otherwise it will cause damage to the meter.

The positive and negative cannot be connected reversely. It will fail to measure the parameters correctly if

connected reversely.

Working temperature -10℃~50℃, storage temperature -20℃~70℃. Should be kept in a dry environment.

Don’t take the instrument apart. There is no component can be repaired by the user in the instrument.
