Moving Coil DC Panel Meters |
General Specifification |
| Principle |
: |
Moving Coil (Pivot-Jewel type), centre core self shielded, suitable for ferrous & non-ferrous panels. |
| Accuracy |
: |
All accuracy classes mentioned refer to IS 1248, BS 89, IEC 51 for Moving Coil Instruments |
| |
|
(10% -100% Full Scale Value). |
| Insulation Resistance |
: |
Over 20 Megohms at 500 V DC. |
| H. V. Break Down |
: |
2000 V AC for one minute between the electric circuit and case. |
| Rectifier Type Instruments: |
: |
These meters have type number with prefix 'C instead of M. Voltmeters with range from 0-10V |
| |
|
to 0-600V. Ammeters with external CT Range 50mA-30A. |
| Interchangable Scales |
: |
MI-72 & MI-96 Meters are with Interchangeable Scales. 75mV Shunt operated meter can be |
| |
|
converted to any range just by changing the dial without opening the cover of the meter. |
