آمپرمتر پنلی دیجیتالی دقیق DC 0-3.0000A

The basic performance parameters of the voltage meter are as follows:
Range: DC0-3.0000A
Display : five 0.36LED digital tube
Display color: red
Refresh speed: > 3 times per second
Measurement accuracy: ± (0.5 ‰ +2 words) (meaning the worst case the maximum error in the table within the normal error of less than 1.7mA) 0.5mA ammeter is difficult to do more than five indicators slightly worse.
Power supply voltage: DC3.5-30V
Operating temperature : -10 ℃ ~ 65 ℃
Opening size: 45.5mm * 26.5mm (open the table directly into the table card)
Dimensions: 48mm * 29mm * 21mm
Temperature coefficient : less than 50PPM / ℃
Features:
1, flexible power supply:  you can use the system to the power supply.
2, small size: Dimensions only 48mm * 29mm * 21mm
3, high precision
 red line : the positive power supply, need to access the DC power range of 3.5-30V positive
 black line : the negative power supply (with the black line through the system to take power when the need to vacant)
Thick red line : the current measurement signal input positive
Thick black line : the current measurement signal input negative
Note: The header needs an independent power supply, power supply range is DC 3.5-30V , access to power supply between the popular black line,
The head will show 0.0000 (very few may appear 1) , then you can bold and thick red line in series to the circuit under test.
 Special attention : (Please carefully follow the instructions wiring, or burned )
This ammeter power supply side and the measurement side of the ground using a common design , that is, the power supply ground and the test side of the ground is connected , so the ammeter test string can only string in the electrical (both under test equipment Of the negative and the device under test between the negative power supply)
It is recommended that the power supply side of the meter head be isolated and isolated .
Instructions for use:
High-precision voltmeter and ammeter in the same system with isolated power supply
