Physical Size: 48x29x26mm (L * W * H)
Opening size: 45x26mm (L * W)
Supply voltage: 3.5 to 30 V (5V or 12V is the best one、 if more than 20V、 please Series connection with 1k ohm)
Lead wire length: 14 cm
Measuring range: DC 0.00-a (current) 0.00 to 33.0 V (voltage)
                                 DC 0.00-a (current) 0.00 to 100.0 V (voltage)
Operating temperature: -10 degrees ~ 65 degrees
Measurement accuracy: Voltage ± (0.3% + 2 digits) Current ± (1% + 2 digits)

Note:
 If you long time to measure the current over 6A、 Please lead directly to the outlet in case of instability of the circuit caused by the temperature of the contact resistance!
Statement of wiring: Red thin wire (vcc): Power + 3.5 to 30 V (Note: If the measurement signal is lower than 30 V and have plenty of power、 it can serve as power supply for the module [black wire and yellow wire are contacted to be used together ])Black thin wire (gnd): Power-measurement signal-3.5 to 30 VYellow thin wire (vin): Signal + (0 to 33.0 v)Red thick wire (I +): Current input + (Connect with the load negative)Black thin wire (i): C Power Input - (negative in series in the power supply)

Ammeter with isolated power supply:

Calibration instructions: Error phenomenon a: Because of some eclectic parts aging and influenced by the temperature、 sometimes when the small current、 the error of a few yards too big or sometimes several meters not? T Show zero without load.Solution: If the meter is the energy、 please short-circuit A and B (connect A and B). Then make the meters have the power、 the meter is automatically calibrated to zero. If the automatic calibration is over、 please disconnect A and B. After this、 that's ok.
