for temperature measurement may not be the same as the users. Therefore, the HP/HS60 series
has been designed to be calibrated in the field by the user. Follow the instructions below if
calibration is wanted or needed.
Note:
To calibrate the unit the user is advised to remove all previously entered calibration data.
To erase the calibration and return to not calibrated readings, press and hold the HEATER button
for three seconds until the display reads CAL. Then press and hold the CANCEL button for
three seconds. Calibration is erased independently for the probe and the plate depending upon
whether the probe is plugged in or not.
PROBE CALIBRATION
Probe calibration is performed by using an accessory calibration kit which precisely simulates
fixed temperature points. The kit has two dummy probes which, when plugged into the probe
jack, represent the value of resistance equal to the temperature shown on the dummy probe. The
dummy probes represent temperatures of 25
Ε
C and 400
Ε
C. These are the probe calibration
points. The kit is available from the manufacturer (HS30-700).
To calibrate the probe temperature, follow these steps.
1.
Insert the 25
Ε
C dummy probe in the probe jack at the rear of the unit. Depress and hold
the HEATER button for 3 seconds until the display reads CAL. Then press ENTER.
Then use the UP/DOWN/RIGHT/LEFT arrows to make the display read 25
º
C. Then
press ENTER. The probe low calibration point is now calibrated.
2.
Remove the 25
Ε
C dummy probe and replace it with the 400
Ε
C dummy probe. Depress
and hold the HEATER button for 3 seconds until the display reads CAL. Then press
ENTER. Use the UP/DOWN/RIGHT/LEFT arrows to make the display read 400
Ε
C.
Then press ENTER. The probe high calibration point is now set.
3.
Remove the dummy probe. The probe calibration is now complete.

PLATE CALIBRATION
The plate calibration does not affect the probe calibration and vice versa. If you are using the
probe temperature control loop only, it is not necessary to calibrate the plate loop. The plate
loop has been factory calibrated and is not likely to change.
To calibrate the plate, an accurate digital temperature meter and a surface temperature probe are
needed. This is a very difficult measurement to make, and not all surface temperature probes
will do the job well. If you need help, please contact the factory. The Plate and Probe
calibration kit #HS30-800 is available from the factory and will contain the temperature meter,
probe, and dummy probes for the probe calibration.
