Ruideng 33v 7in1

Description: Brand: RD Voltage measuring range: DC0.00-33.00V Current measuring range: DC0.000-3.000A Input voltage: 4-20V Ambient temperature: -15 ~ 65 ￢ﾄﾃ Dimensions: 48 * 29 * 22 (mm) Button Function Instruction: In the display interface, click the button to switch data set; keep pressing button to clear the accumulated data to zero. The component aging and temperature variation after long-term use may appear tiny error when it measures small current. To avoid this error, you can unplug the current wire socket and keep pressing the button to connect power supply, until the screen display “AAA”, then loose button. The Wiring Diagram Instruction: Please ensure proper wiring in strict accordance with the wiring diagram. Using Isolated Power Supply The two power supplies must be isolated and don’t connect any load. The highest voltage of isolated power supply is 20V Using DC-DC converter to power supply 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. Using system to power supply The black thin wire connects nothing and you should use insulator wrap it to avoid short circuit. Package included: 1 x RUIDENG 33V/3A 7in1 Blue OLED Multifunction Tester Meter With Cable

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 ~60°c                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:  ①Run time ②Power display ③Data set ④Temperature display ⑤Capacity display ⑥Voltage display ⑦Current display ⑧Energy 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: ①Red thin line ②Black thin line ③Yellow thin line ④Red thick line ⑤Black thick line ⑥Load 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.
