Different probes require controls therefore, it is possible to download different
drive routines for the instrument from a PC.
There is a possibility to adapt how to measure by adjusting the timers and Purge
Level.
Probe Type
Select the connected probe. Choose between “
Hand Probe
” and another probe
driver installed from the disc delivered with active probe (if ordered).
APC Time A-D
Adjustable timer used by the APC system. Select a APC timer and press “Enter” to
display specific use of this timer. APC timer can be used for general purposes in a
custom APC program.
Purge Level
Signal level controlling the Purge_Level APC Triggers. Standard probes that support
active sampling use the
Purge Level
for fast interruption of sampling that result in
high gas signals.
Setting
Purge Level
equal to, or just above,
Reject Level
will give the fastest possible
cycle times for those probes.
Quick purging also enhances signal repeatability.
Note:
Purge level interrupts active sampling of APC probes. This means that higher
signals will be underestimated as the sensor is purged before full signal has
developed.
8.8 Display Settings
This section describes the different display settings of the Sensistor ISH2000
HySpeed.
Contrast
Contrast level of display. Higher value gives higher contrast. The contrast may need
adjustment if ambient temperature changes.
Brightness
Brightness of the display lamp. A lower brightness value saves energy and prolonges
the lamp.
Invert Colors
Change the black to white and white to black. Useful in a dark environment to keep
a high readability.
Screen Save Timeout
Display lamp will dim to half brightness if instrument is left idle for the number of
minutes set by this parameter. The screen save timeout can be set between 1 and 60
minutes, the function is deactivated if set to OFF. The display lamp will return to the
