ICO 51 is a programmable digital panel meter 72 x 24 mm for electrical measurements in 10,000 points. It allows DC and AC voltage to be measured up to 400 V (true effective value with or without component continuous health) and DC and AC current to be measured up to 5 A using a small shunt screwed on the back connector.
- Panel meter size: 72 mm x 24 mm
- IP65 protected
- Measurement, display and scaling of:
- DC and AC voltage up to 400 V
- DC current up to 2,000 A with an external shunt
- AC current up to 200 A + Current transformer, with secondary current of 1 A or 5 A
- Frequency up to 5,000 Hz
- 9 different power supplies available

Automatic ranging
Further features
| Measurement hold | Short-circuit on the rear panel |
| Scaling | The value is to be entered using keyboard, while the value of measurement corresponding can be is introduced of the same way, is measured by the instrument. This possibility is very interesting for error corrections on temperature ranges. |
| Sampling rate | 2.5 samples / s |
