7. Immerse the temperature probe into the second vessel as close as possible to the reference
thermometer. Allow a few seconds for the probe to stabilize.
8. Press the / keys to set the calibration point value to that of the hot water.
9. When the reading is stable and within range of the selected calibration point, press displayed
CFM
functional key to confirm. The instrument returns to measurement mode.
Note:
Press / keys to change calibration point if necessary (±10.0
°
C) around the point.
If the reading is not within range of the selected calibration point, “Wrong” message will blink.
Change the temperature probe and restart calibration.
mV Calibration
A two point calibration can be performed at 0 mV and 1800 mV.
1. Attach to the BNC connector a mV simulator with an accuracy of ±0.1 mV.
2. Enter the calibration screen. Press
mV
functional key.
3. Set 0.0 mV on the simulator.
4. When the reading is stable and within range of the selected calibration point, press displayed
CFM
functional key to confirm.
5. Press
CFM
to confirm. The second calibration point of 1800 mV will be displayed.
6. Set 1800.0 mV on the simulator.
7. When the reading is stable and within range of the selected calibration point, the
CFM
functional
key is displayed.
8. Press
CFM
to confirm. The instrument returns to calibration screen.
9. Press
ESC
key to return to measurement mode.
Notes:
If the reading is not within range of the selected calibration point, “WRONG” tag will
blink. Verify calibration condition or contact your local Hanna Instruments Office.
Press CAL or ESC during calibration to return to measurement mode.
