Function:

ST-9040L single phase reference meter is a new generation measuring instrument with whole microprocessor control, multi-functions, high accuracy, easy to use and convenience for portable which suitable for the worksite or laboratory to test voltage, current, power, phase indicating meters.

It adopts digital multiplier principle and technique, could proceed to four quarters measurement. Voltage wide ranges need not to turn over the range. Current input adopts two methods with direct input or by the clamper. With the clock device for test data register, inquiry, reading meter function etc., and could proceed with microprocessor for data delivery and management.
