TEMPERATURE CALIBRATION

• Prepare a beaker containing

crushed ice and water at 0°C (32°F)

and another one with hot water at

25°C (77°F) or 50°C (122°F).

• Use a Checktemp or another cali-

brated thermometer with a

resolution of 0.1° as a reference

thermometer.

• Immerse the temperature probe in

the beaker with ice and water as

near to the Checktemp as possible.

• Once visualized the selected output, press the  key to

choose the range of the analog output (0-20 mA or 4-20

mA); then press the CFM key to confirm the choice.

• Once selected and confirmed the

range for the analog output, the

secondary LCD shows the first point

of calibration (1 or 4 mA) and the

primary LCD displays the range of

the actual calibration.

• With the tester check the real current value provided by the

instrument at the output port. If this value is different from

the expected one, it is possible to change the current

erogated by the instrument pressing the  or  key.

• Adjust the value until it matches with the first point of cali-

bration, then press CFM to confirm. The instrument will

turn to the second calibration point (20 mA).

• The calibration procedure is the same as for the first point.

• Once the instrument is calibrated for both points (and con-

firmed), it will exit from the calibration menu.
