The desired sensor type is easily set, press the Scroll key until the lower display indicates,
In.Typ
The upper display will show the current set sensor type,
J.tc
J thermocouple
K.tc
K thermocouple
L.tc
L thermocouple
r.tc
R thermocouple (Pt/Pt13%Rh)
b.tc
B thermocouple (Pt30%Rh/Pt6%Rh)
n.tc
N thermocouple
t.tc
T thermocouple
S.tc
S thermocouple (Pt/Pt10%Rh)
PL.2
PL 2 thermocouple
rtd
100 Ohm platinum resistance thermometer.
T012
E thermocouple
Again the value can be modified with the UP and DOWN keys.

Enabling/Disabling Custom Calibration
Custom calibration allows the indicator to be programmed to suit a particular temperature sensor.
This allows the indicator to automatically show the true temperature, without having to manually
apply a correction.
When the Custom or User Calibration is active the indicator will show the REM beacon lit
continuously. The use of User calibration can make a significant difference to the accuracy of the
instrument, and this REM beacon provides a clear and continuous indication of the calibration
status. Isotech will configure and set user calibration when the Dry Block is ordered with a
temperature sensor.
To alter the calibration status press the Scroll key until the lower display shows,
UCAL
The upper display will indicate either,
ON
for user calibration
Or
OFF
for factory calibration of the indicator
Use the UP and DOWN keys to toggle between the two values.
When calibrating an unknown sensor against a calibrated probe it may be necessary to switch
the calibration off for the unknown, and on for the calibrated probe.
14.7
Instrument Address
Like the controller, the indicator has a configurable "address" which is used for PC
communications. Each instrument has an address; this allows several instruments to be connected
in parallel on the same communications bus. The default value is 2 (The controller defaults to 1).
This address would only need to be changed if more than one Dry Block is connected to the same
PC port.
