1 Features
Designed for measurement of DC voltage or DC current, temperature through Pt100
thermometers, J, K thermocouple, AC voltage and AC current.
4-digit LED display (20 mm digit height)
Programmable parameters through the PD14 programmer
- Precision of displayed results (decimal point)
- measurement averaging time
- recounting of indications (individual characteristic)
- automatic or manual compensation: temperature of cold ends (for J, K) or wire resistance
(for Pt100)
