Do not change the calibration values or control parameters from the factory-set values
unless recalibrating the Product. The correct setting of these parameters is important
to the safe and proper operation of the Product.
The parameters in the CALIB menu are set at the factory and must not be altered unless recalibrating
the Product. Recalibration of the Product should be performed by qualified personnel. The correct
values are important to the accuracy and safe operation of the Product. Access to these parameters is
password protected. In the event that the calibration parameters need to be reentered into the Product,
the constants and their settings are listed in the Report of Calibration shipped with the Product.
CONT SETUP
Use the CONT SETUP (CONTROL SETUP) to access the controller parameters.
TEMP PBAND
The TEMP PBAND parameter is the proportional band in °C that the Product's proportional-integral-
derivative (PID) controller uses for control.
TEMP INT
The TEMP INT parameter is the integration time in seconds that the Product's PID controller uses for
control.
TEMP DER
The TEMP DER parameter is the derivative time in seconds that the Product's PID controller uses for
control.
IR CAL
The IR CAL (IR CALIBRATION) menu contains the IR target calibration constants: IR CAL 1, IR CAL 2,
and IR CAL 3. Use the arrow buttons to enter the set-point for each calibration point and push ENTER
to accept the entry. The calibration points should be selected applicable to model with a low, mid-
range, and high set-point.
IR CAL 1
The IR CAL 1 parameter is the offset in °C for the IR target accuracy at the 1st calibration point.
IR CAL 2
The IR CAL 2 parameter is the offset in °C for the IR target accuracy at the 2nd calibration point.
IR CAL 3
The IR CAL 3 parameter is the offset in °C for the IR target accuracy at the 3rd calibration point.
WAVELENGTH
The WAVELENGTH parameter can be set to the default 8 µm to 14 µm or USER selectable. This is to
remind the user that the nominal emissivity and calibration of the Product pertains to the 8 μ m to 14 μ m
band.
CALDATE
The CALDATE parameter is the calibration date for the IR target. Use the arrow buttons to enter the
calibration date in the format yyyy,mm,dd.
