3. Remove the union nut by hand. The o-ring in the union nut creates some friction.
4. Remove the probe tip by drawing it straight out.
5. Mount a new probe tip. Make sure it is in correct position.
6. Observe the contact area between the probe pipe and the probe neck. They
should contact each other.
7. Refit the union nut.
8. Tighten with a 10 mm wrench.
8.15 Probe Control Port
The Sensistor ISH2000 is equipped with a parallel Probe Control port. This Probe
control port can be used for controlling active probes, feeding status signals to a
supervising computer system.
Note: Battery operated model Sensistor ISH2000C does not have a Probe Control Port .
Pin configuration for the different detector models is described under Model
Specific Specifications below.
See “Sensistor ISH2000 specifications” on page 50 for electrical specifications.
See “Status signal patterns” on page 38 for signal patterns.
Probe Control Port Connector
The control port connector is a 25-pin female D-sub. Refer to Table 8-2 for the pin
configuration.
Table 8-2. Pin configuration.
CAUTION!
The Probe Control Port (25-pin D-type) on the
back of the instrument is not a computer or
printer port. Connecting a printer or any other
computer device may cause permanent damage
to the connected device.
