7.2 COMMISSIONING MODE FUNCTIONS
7.2.1 Internal Date / Time
The date and time are used in the transmitter to run time based operations such as impedance
readings and gas calibration checks. The correct date and time should be entered by pressing and
holding the OPTION UP & DOWN keys. The date and time will change faster the longer the OPTION
key is held.
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
The 9060Z 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 as a single probe device you should set the number of probes to
‘single probe’ to disable all probe 2 alarms and display items.
7.2.4 Probe 1 & 2 Type
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
The thermocouple type can be set to K, J, R or S. The thermocouple in the Teledyne Analytical
Instruments 9060H heated probes are always K type. 9060UL/UH 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
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.
7.2.7 Transmitter Output Channel 1 & 2
The 9060Z transmitter has two fully configurable 4‐20mA analogue outputs. The channels can be
configured independently to output one of several calculated values.
