Replacing The Battery
The instrument will indicate 'BAT LOW' when the battery
needs changing.
To change the battery, firstly remove the unit from the
outer case. The battery compartment is on the rear of the
instrument. Using a small screwdriver ease back the tab
of the battery compartment. The compartment will then
lift away.
Open Circuit Thermocouple Detection
An error in the probe is shown on the display by a series
of bars '- - - - -' coupled with the word 'INPUT' at the top
of the display. This indicates either that the probe has an
error or the temperature is out of range.
Simulate Thermocouple
This instrument is capable of simulating a thermocouple,
thus enabling it to be used to check the calibration
accuracy of any other thermocouple instrument/controller.
To change to the simulate mode press both arrow keys
simultaneously. Simulate mode is indicated by a solid bar
on the left of the display. To cancel this mode, simply
press both arrow keys again. When in simulate mode, the
set point is shown on the main display and may be
changed using the arrow keys. The second display
indicates the actual output of the unit. When the two are
equal the output has settled and as a further guide a
second bar is activated in the left of the display.
To avoid cold junction errors, the test equipment and the
simulator should be at the same ambient temperature.
