Changing the Probe
After attaching a probe the Sensistor ISH2000 HySpeed needs to stabilize, and the
green LED should blink. If it does not, then there is a fault in the cable or the
hydrogen sensor inside the probe is faulty.
When the stabilisation period is over the green LED should stay on. Before using the
Sensistor ISH2000 HySpeed the instrument needs to be calibrated. Repeat
calibration after one hour to achieve greatest accuracy.
8.13 Probe Control Port
The Sensistor ISH2000 HySpeed 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, and for simple test fixture control.
Pin configuration for the different detector models is described under Model
Specific Specifications below.
See “Sensistor ISH2000 HySpeed specifications” on page 43 for electrical
specifications.
See “Status signal patterns” on page 32 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.
