PINOUT & WIRING DIAGRAM
Because long cable lengths are common some electrical factors should be taken into account and
these are discussed below.
There are two wiping protocols available on the NEP-9500 probes:
1. A single wipe externally initiated by momentarily reseting the probe (specify
during the ordering).
2. A periodic automatic wipe (specify during the ordering).
Voltage Output version
ANALITE NEP-9500 probes may have an analogue voltage output with a nominal
output impedance of 500 ohms. For particularly long cable runs, the 4-20mA current
output version is recommended.
