Hold Channel Alarms:
This only applies to the multi-channel Rapidox
1100ZR3 analyser that is fitted with a multiplexer and is greyed out in this
version.
5)
Measure Delay (s):
This only applies to the multi-channel Rapidox 1100-
ZR3-H-PFC analyser that is fitted with a multiplexer and introduces a time
delay in seconds to allow gas from channels 1/2/3 to flush away before the
software alarms become active again.
6)
Flow Alarm Set Point (mbar):
Use this parameter to set a pressure value in
mbar so that if the gas flow going into the analyser gets impeded in any way
then the pressure reading will drop below zero (i.e. the sample pump will
create a vacuum) and the low flow warning alarm will trigger below this
point.
7)
U/Range Alarm:
Use this parameter to set the U/Range alarm condition to
-5 (enabled) or 0.5ppm (disabled). When enabled the fault code -5 is sent to
indicate that the Rapidox sensor reading is under range (i.e. reading below
0.5ppm oxygen). When disabled any readings less than 0.5ppm are
reported as 0.5ppm.

DDE Protocols
For the Rapidox software to communicate with the main oven software using DDE
please refer to the following list of possible links that are currently used:
PFCControl state: 0 = Off, 1 = Monitor Only, 2 = On
"RAPIDOX|Main!PFCControl"
Remote Data Acquisition: "RUN", "PAUSE", "RESUME", "STOP"
"RAPIDOX|Main!ACQControl"
Desired O2 level in PPM: High and Low window set as PPM/- 20ppm.
Included for backwards compatibility
"RAPIDOX|Main!PPM_level"
Desired O2 level window in PPM
"RAPIDOX|Main!HighO2SetPoint"
"RAPIDOX|Main!LowO2SetPoint"
Current O2 level in PPM
"RAPIDOX|Main!lbl_PPM_O2"
Set to -1 when not measuring (see Error state for reason), -4 to indicate sensor fault
and -5 to indicate under range error. Note the under range error can be disabled
using the drop down box shown in Figure 23 above and when it is disabled the
reading will be fixed at 0.5ppm in an under range condition.
