The powerful indicator N1500 offers among its universal input and the 2 relay outputs for the monitoring of the threshold values many other functions. The Min.- and Max.-values can be prompted with just a keystroke. Also there is a Hold and a Peak-Hold Function whose readouts can be deleted using either the function key or the digital input. The high tact frequency of 15 measurements/second (5 measurements/second when using linear input, manufacturer of thermocouples or Pt100) allows the N1500 indicator to monitor fast processes. It offers also the possibility to linearise the measurement signal when using non-linear input signals (mV, V, mA).
