Phase sequence
If the phase sequence of “U1, U2 and U3” or “I1, I2 and I3”
is positive, then the cursor flashes from left to right in
order; if negative, then from right to left.
Testing rate
About 2 seconds per time
Data hold
When the button “HOLD” is pressed during test, the data
will be held and the symbol “HOLD” is displayed.
Data storage
500 groups of data
USB port
Upload stored data to computer via USB port, so as to
analyze and manage data.
Auto power off
To reduce power consumption, the voltammeter powers
off automatically 15 minutes after it is powered on.
Backlight function
Used in dark environments and at night.
Voltage detection
If the battery voltage is lower than 3.0V, the low battery
symbol is displayed to indicate charging in time.
