SELECTION SWITCHES ON DIP SWITCH (SEE TABLE 1)
• Switch the Power Supply switch (Pin no. 1 on DIP Switch), to the ON position.
• Select the desired Temperature Sensor by using Pin no. 2 of the DIP Switch as per the table given below.
• If Thermocouple Sensor is selected on Pin no. 2, then the type of Thermocouple may be selected by Pin no. 3 of
the DIP Switch.
• Select the desired temperature units between ° F and ° C by means of Pin no. 4 of the DIP switch.
• The display will update to the selected units after the measurement cycle of approximately ten seconds.
• The indicator will immediately indicate the process temperature on the LCD display.
BATTERY REPLACEMENT
• Two nos. Batteries (type AA, 1.5V).
• The instrument has minimal power requirements. However, when the LOW BATT sign appears on the display, it is
time to replace the batteries.
• When LOW BATT is indicated, or if the instrument has been unused or Power OFF condition for an extended
period, the batteries must be replaced immediately.
USER SETTINGS
• On the rear card, there is a four-way DIP switch. The settings are as follows:-

CONFIGURATION
All settings and adjustments must be done from the rear side of the unit.
CONNECTIONS
•
Locate the green terminals on the lower rear section of the unit.
•
Connect the RTD (3 wire Pt 100) or the Thermocouple sensor input at these terminals in the correct polarity.
•
Minimize the number of junctions between the Thermocouple and the Indicator.

•
Switch No. 1 is used to turn the unit ON or OFF. This switch is provided to save battery life when the unit is not in use for an
extended period of time.
•
Switch No. 2 is a selector switch which allows the user to select between a RTD sensor (Pt 100) input or a Thermocouple input. If
an RTD is used, this switch should be in the “OFF” position.
•
Switch No. 3 allows selection between a Type J or Type K thermocouple input, when switch no. 2 is in the “ON” position. This
switch is not used when RTD sensor (Pt 100) is selected.
•
Switch No. 4 is a selector switch which allows the user to display temperature in either degrees C or degrees F. The “OFF”
position of this switch will display degrees F.
