7.2.2 Service Date

The service date can be used to keep a record of when a probe was changed. The Runtime timer which
keeps a track of the hours and minutes that the transmitter and probe has been operating is reset when the
service date is changed.
The service date and the runtime timer can be displayed as lower line items in Run Mode.

7.2.3 Number of Probes

Options: Single Probe / Dual Probe
Default: Single Probe
The 1732 transmitter can operate in single or dual probe mode. By selecting single probe, all dual probe
options and alarms will be disabled and second probe options hidden from the user.
If you are using the transmitter with a single oxygen probe, setting the number of probes to 'single probe' will
disable all probe 2 alarms and display items.
7.2.4 Probe 1 & 2 Type
Options: 1231 / 1234 Heated
1232 Unheated
Default: 1231 / 1234 Heated
The probe type function allows a selection between a heated probe and an unheated probe types. Heater
control and alarms will be disabled if unheated probe type is selected.
7.2.5 Probe 1 & 2 Thermocouple Type
Options: K-Type / J-Type / R-Type / S-Type
Default: K-Type
The thermocouple in the Novatech 1231/1234 heated probes are always K type. 1232 unheated probes are
available in R type or S type. Other thermocouple options are made available for special installations.

7.2.6 Auxiliary Thermocouple Type

Options: Disabled / K-Type / J-Type / R-Type / S-Type
Default: Disabled
When the transmitter is operating as a single probe mode, the probe 2 thermocouple input (terminals 7&8) is
used as an auxiliary thermocouple input. In dual probe mode this option is unavailable.
Use of an auxiliary thermocouple allows for basic monitoring of temperature as well as enabling the
calculation of combustion efficiency. The thermocouple type can be set to K, J, R or S.
