Low Cost 5 Digit Panel Meter
N25 Panel Meter
Destined for measurement of d.c. voltage or d.c. current,
temperature through Pt100 resistance thermometers,
J, K thermocouples, a.c. voltage and a.c. current.
5 LED digit display with 15 mm digit hieght.
Parameters programmable by PD14 programmer:
precision of displayed results (decimal point),
measurement averaging time,
recounting of indications (individual characteristi c),
automatic or manual compensation: cold juncti on
temperature for measurement with thermocouples
or wire resistance for measurement with Pt100 (N25T).
