Square Type Moving Coil DC Ammeters
1. Model: 90°SF-144-3,SF-96-3,SF-72-3,SF-48-3.
These meters measure the DC current with linear scale. The nominal mark is C.
2. Accuracy: Class 1.5.
3. Specification: 100uA, 500uA, 1mA 2mA, 5mA, 10mA, 20mA, 30mA, 50mA, 75mA, 100mA, 150mA, 200mA, 250mA, 300mA, 500mA, 1A, 3A, 7.5A, 10A, 20A, 30A, 50A, 60A, 75A, 100A. For 10A -10KA, use external 75mV, 65mV or 45mV shunt.
4. Notes: For 50A 60A 75A 100A meters, when these meters directly connected to circuit, their accuracy is class 2.5.
5. Case: Non-combustile ABS plastic material is used for making SF series'external case,and PPO plastic material is used for SF series's base; while Non-combustible PC plastic material is used for making SFT series'external case and base. Both of which will not suffer deformity under long-term use at 70 and 120 respectively.
6. Changeable scale: Scale can be changed without opening meter, convenient to use, effective dust proof. Under the same input signal, scale-change can be conducted without loss of accuracy or damaging the meter.
7. Mounting: SF series is flush mounting with bracket.
