DPS Black Abs Plastic Current Measurement 220V Digital dc Current Meter Voltmeter
DPS digital display ac dc voltage and current dual display meter is to simultaneously display the measured AC voltage and ac dc current on the instrument Widely used in power distribution cabinets, household power distribution boxes, home appliance repairs, etc.
Operating instruction
When meausuring, changing range and calibrating zero, it must be connected with the corresponding shunt.
Changing range operation:
Factory default is 100A measuring range; if switch to 50A range,please connect 50A shunt and keep pressing the key to power on, until the screen displays "50A", then loose the key. Now changing range is done. If you want to switch to 100A range, please connect 100A shunt and operate by same way.
Calibrating zero operation
With the aging of components and influence of ambient temp, there might be tiny error for the current reading, especially when measuring low current. To calibrate it: 1, power off the meter.2, connect the shunt and disconnect the load. 3 press and hold the front button .4, power on the meter.5, release the button when you see “AAA” on the screen. Done
Button Function Instruction:
This tester has 0 and 1 two data groups; and data groups are switched by pressing the key.
When data group is the 1 group, the current capacity and energy will be stored after power off. And the stored values will be accumulated after power on. When the data group is the 0 group, the current capacity and energy will be stored after power off; when power on next time, the stored capacity and energy are blinking displayed. But when the new capacity is up to 0.01 Ah, the stored capacity and energy will be covered, and the values will start over. At the two data groups, the accumulated values can be cleared to zero by keeping pressing the key.
