6.3.1 Probe 1 Offset
Each Novatech probe has an offset calibration value printed on a tag that is attached to the probe when it is
dispatched. To achieve accurate measurement the offset value must be entered with the same polarity as it
is printed on this label. The offset value should be within ±1.0mV
NOTE: An offset of 1.0mV will change the oxygen reading by approximately 1% oxygen when the probe is in
ambient air. However, as the process oxygen measurement drops, this offset will have a reduced affect. At
a process gas oxygen concentration of 2%, the 1.0mV offset error will only change the reading by 0.1%
oxygen.
If in any doubt about the correct offset value, set it to 0.0mV.
The function ’Probe 2 Offset’ will only appear if the transmitter has been configured for 2 probes. (see
chapter 7.2.4 )
6.3.2 Lower Line Items
This function allows the operator to change the items that are available to be displayed on the lower line of
the transmitter in RUN mode. If the word “Enabled” appears on the display for a selected lower line option,
the measurement will be available to be shown on the display in the RUN mode by scrolling through the list
using the DISPLAY UP and DISPLAY DOWN keys.
A lower line measurement can be “Enabled” or disabled by pressing the ENTER key.
