PROGRAM USING FRONT PANEL
Insure that switch 1 is in the “ON” position and switch No. 4 is in the desired position for correct indication of
temperature (“ON” = deg C, “OFF” = deg F). The three keys on the front panel are as follows:
PROG
P
The PROG or PROGRAM key is the central coordinating key to browse the settings of the
instrument. Pressing this key allows the operator to sequentially view, change, and save the
parameters.
INC
The INC or Incrementing key allows the operator to select the numeral in the digit being set on an
increasing scale. The digit will sequentially display 0, 1, 2, …9 on each pressing of the INC key.
DEC
The DEC or Decrementing key allows the operator to select the numeral in the digit being set on
a decreasing scale. The digit will sequentially display 9, 8, 7,…1 on each pressing of the INC key.
Model DT-8300EX
SET-UP
The unit is factory calibrated using a RTD sensor, so the display will be in deg C or deg F (as selected) if an RTD sensor
has been connected. If a thermocouple is connected, then the display will be “Err”.
The sequence of settings is as follows:

The unit is factory calibrated using a RTD sensor, so the display will be in deg C or deg F (as selected) if an RTD sensor has been
connected. If a thermocouple is connected, then the display will be “

The sequence of settings is as follows:-
KEY PRESS
DISPLAY
DESCRIPTION
Press both keys simultaneously for at least 10 seconds.
The display alternates between Sen (sensor) and the sensor options. The
desired sensor may be selected at this point. To select a particular sensor, the
increment or decrement key should be pressed (as required) for one cycle time.
Alternate display for RTD / RTD.1 option.
After selecting the sensor, say RTD, the PROG key should be pressed.
Error correction of the display can be done at this stage. The display will
alternate between
EΓ
C and 000. The indicated temperature can be forced up or
down on the temperature scale by 20 degrees for any corrections in non-
linearity or errors on account of long Cables, Sensor faults etc.
This indicates an Error condition. It could mean either a broken sensor, or open
sensor or abnormally high temperature, or wrong sensor input.
Press both keys simultaneously for at least 10
