User Guide

Note Press SETUP before CFM to exit without changes.

Note It is suggested to calibrate the offset before entering the cali-

bration buffer direct selection.

TEMPERATURE CALIBRATION

The controller is factory calibrated for temperature. However,

the user may also perform a one point temperature calibra-

tion. This procedure is to calibrate the offset only; the slope

will remain as factory calibrated.

• Prepare a beaker containing a solution at a given tem-

perature inside the range of the meter.

• Use a Checktemp or a calibrated thermometer with a

resolution of 0.1° as a reference thermometer.

• Immerse the temperature probe in the beaker as close to

the Checktemp as possible.

• Press and hold first CFM and

then CAL to enter the tem-

perature calibration mode.

• Execute the password proce-

dure.

• Select code 1 via the arrow keys for temperature calibra-

tion and confirm with CFM.

• CAL will blink on the LCD. The measured

temperature will be displayed on both the

primary and secondary LCD.

• Use the arrow keys to set on the secondary LCD the tem-

perature read by the reference thermometer.

• When the reading has stabilized at a value near the cali-

bration point, CAL will stop blinking and an intermittent

CFM will prompt the user to confirm the calibration.

• If the reading stabilizes at a reading significantly variant

from the first setpoint, an intermittent ERROR will prompt

the user to check the beaker or bath.
