The plate surface calibration procedure cannot be done with the temperature probe
plugged into the rear of the unit
. The calibration starts at the low temperatures and goes high.
It is time consuming. Before making an adjustment, be sure that the plate temperature has
stabilized at the point being calibrated. That often takes 20 to 30 minutes after the target
temperature is initially reached. Follow the procedure below.
1.
Start at room temperature. Using your temperature meter, read the plate surface
temperature in the center of the heater plate. Press and hold the HEATER button for 3
seconds until the display reads CAL. Then press the ENTER button. Use the
UP/DOWN/RIGHT/LEFT arrows to input the temperature measured for the plate
surface.
Then press the ENTER button. The plate low calibration point is set.
2.
Set the PLATE temperature to 350
Ε
C. The plate will start to heat. Give the unit ample
time to reach and stabilize at 350
Ε
C. When the temperature is stable, measure the plate
temperature with your meter. Press and hold the HEATER button for three seconds until
the display reads CAL. Then press the ENTER button. Use the
UP/DOWN/RIGHT/LEFT arrows as needed to make the plate temperature display read
what is measured on your meter. Then press the ENTER button.
3.
Let the unit cool back to room temperature. It will take some time. You can speed the
process by using a fan to help cool the plate. After about an hour measure the plate
surface temperature again. Then reset the plate temperature to what the meter reads as
was done in step 1 above.
The plate surface calibration is now complete.

XIII. CLEANING, MAINTENANCE, AND CONSUMABLE PARTS
Cleaning
These units are subject to splashes and spills during normal use. Be sure to clean all spills
quickly. Wipe spills with a soft cloth or paper towel. If a cleaning solution is necessary, use a
mild soap or detergent solution and a soft cloth. Be sure not to use solvents. They could damage
the paint, labels or display window on the unit. A mild abrasive can be used to clean the ceramic
glass heater surface. Do not use abrasives on the cast aluminum heater top. It will scratch the
surface.
Note: When using these units with corrosive liquids, the vapors coming off these liquids
may get into the chassis of the unit and cause damage. This is particularly true on the 5-
