RIDEN® 100V/20A 7in1 OLED Multifunction Tester Voltage Current Time Temperature Capacity Voltmeter Ammeter Electrical Parameter Meter

Technical Parameters: Voltage measurement range: DC00.0-99.9V Current measurement range: DC00.0-20.0A Time measurement range: 0-99h59min Power measurement range: 0-999.9-2000 W Temperature measurement range: -15 c ~60c Capacity accumulation range: 0-999.99-9999.9 Ah Energy accumulation range: 0-99999Wh-9999KWh Voltage measurement accuracy: (0.5% + 2digits) Current measurement accuracy: (1% + 2 digits) Product weight: 33g Product size: 48mm*29mm*22mm (L*W*H) Display Interface Instruction: Run time Power display Data set Temperature display Capacity display Voltage display Current display Energy display 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 0.01Ah, 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. Zero calibration 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, 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 The Wiring Diagram Instruction: Red thin line Black thin line Yellow thin line Red thick line Black thick line Load Please ensure proper wiring in strict accordance with the wiring diagram. Using Isolated Power Supply to power the meter The two power supplies must be isolated and don't have any connections between them. The voltage of the isolated power supply must be less 60V Using system to power the meter The black thin wire connects nothing and you should use insulator wrap it to avoid short circuit. Using DC-DC converter to power the meter The black thin wire connects nothing and you should use insulator wrap it to avoid short circuit. The DC-DC converter must be common cathode structure. Package included: 1 x 100V/20A 7in1 OLED Multifunction Tester
