Range | DC0-3.0000A, the maximum reservation can be measured 5A, the accuracy above 3A has a slight impact |
Display | 5 digit 0.36 inch LED |
Digital tube display color | Red / Blue can be optional |
Refresh rate | >3 times per second |
Measurement accuracy | ± (0.5 ‰ + 2 words) (meaning that the maximum error of the table is within 1.7mA, the normal error is less than 0.5mA) |
Supply voltage | DC3.5-30V |
Working temperature | -10 ° C ~ 65 ° C |
Opening size | 45.5mm*26.5mm (the opening directly snaps the watch into the panel) |
Dimensions | 48mm*29mm*21mm |
Temperature coefficient | less than 50PPM / °C |
Special attention | Please follow the instructions carefully, otherwise the consequences of burning will be conceited |
The meter head needs independent power supply, and the power supply range is DC 3.5-30V. When the power supply is connected between the thin red and black wires, the meter head will display 0.0000 (extremely 1 may appear), then you can change the thick black line to the thick The red wire is connected in series to the circuit under test.
1. The ground wire of the power supply terminal and the measurement terminal of the ammeter adopts a common ground design. Between the negative pole of the device and the negative pole of the power supply of the device under test)
2. It is recommended to use a separate isolated power supply for the power supply end of the meter (which can effectively prevent the ammeter from being connected in series with the positive electrode to burn the meter)
Please compare the accuracy of this ammeter with at least a five-and-a-half-digit multimeter. This product uses a six-and-a-half-digit multimeter as the products calibration instrument to ensure the products extremely high accuracy.
The current range of ordinary multimeters is relatively poor in indicators, so when comparing the test, please compare the equipment-be sure to leave enough room for accuracy, otherwise the reliability of the result is not high. In other words, general multimeters basically cannot keep up with the calibration accuracy of this meter.
