CAUTION: FOR STANDARD INSTALLATIONS THIS IS A FACTORY ADJUSTMENT. DO NOT USE THE PREAMP GAIN
MENU FOR CALIBRATING SENSORS. IT SHOULD ONLY BE ADJUSTED IF A NEW MEASUREMENT GAS OR INPUT RANGE
IS REQUIRED.
8.5.3 ZERO CAL VALUE (TECHNICIANS ONLY!)
The Zero Cal Value Menu entry allows the zero-calibration value to be set for something other than a zero reading.
In rare cases, it may be necessary to perform Zero calibrations at some other engineering unit reading than zero.
IMPORTANT! DO NOT EXCEED 25% OF FULL SCALE.
8.5.4 RAW MIN / MAX COUNTS (TECHNICIANS ONLY!)
The Raw Min / Max Counts Menus determine the range of 12-bit analog to digital (A/D) converter counts that define
0 and 100% of full scale. The default range is 800 – 4000 counts. Raw Min A/D counts create 0% readings, and Raw
Max A/D counts create 100% readings.
The corresponding Zero 0% and Span 100% readouts that appear on data displays are entered in the Channel
Configuration Menu described in see Sections 8.2.3 and 8.2.4. Live A/D count input values may be viewed on the
Preamp Gain screen and the CAL MODE Information screens described see Sections 8.5.2 and 8.5.3.
8.5.5 RF LINK TEST (TECHNICIANS ONLY!)
The RF LINK TEST shown in Figure 7 6 is a diagnostics tool which allows readings of 0%, 25%, 50%, 75% or 100% of
the full-scale range to be broadcast to any controller and/or wireless relay on the same network. Alarms may also
be sent by filling the check box.
After the menu is ready:
1. Point to the TRANSMIT PACKET Menu.
2. Swipe the EDIT key–the broadcast is made every time the EDIT key is swiped.
NOTE: RF LINK TEST is very useful for troubleshooting and testing a new installation.
IMPORTANT! WTC & WAR RELAYS DO ACTIVATE IF ALARMS BOXES ARE CHECKED!
8.5.6 Sensor Comp Table (TECHNICIANS ONLY!)
Signals from electrochemical sensor elements used in TXP-WTA Sensor Transmitter Smart Sensor modules may be
affected by temperature extremes. Sensor transmitter Smart Sensor Modules are equipped with an on-board
temperature sensor which TXP-WTA Sensor Transmitter temperature of the sensor element.
Sensor types have a matching Temperature Compensation profile which is stored with each Smart sensor in the
table shown in Figure 7 7.
