Unbalance Test Wiring Diagram)
Connect phase-A voltage terminal of the test equipment and phase-A voltage terminal of the
instrument with a yellow wire, and connect phase-B voltage terminal of the test equipment and
phase-B voltage terminal of the instrument with a green wire, and connect phase-C voltage
terminal of the test equipment and phase-C voltage terminal of the instrument with a red wire;
Three clamp current transformers are used to measure A, B, C three-phase current of the device.
You can view the measurement results in the "Unbalance Interface" screen after done with wiring.
VI Battery Maintenance and Charging
The instrument uses a high-performance lithium-ion rechargeable battery as an internal
power supply. Operator can not easily replace other types of batteries, in case causing damage to
the instrument for electrical level is not compatible.
The instrument should be promptly charged, in case that deep discharge battery affects the
battery life.
Charge it everyday if it’s possible under normal use (Better to charge it once a month if not
used in the long-term), so as not to affect the use and battery life. Charging time should be at least
six hours every time. The instrument can be continuous charging due to the internal charging
protection function.
Each time when you remove the battery from the instrument, battery protection board inside
the instrument will automatically enter protection status. Re-insert the battery, and the instrument
can not work directly, you need to give power to the charger to rescind the protection state before
working properly.
