TEMPERATURE CALIBRATION (for technical personnel only)

The Mi 170

Mi 170

Mi 170

Mi 170

Mi 170 is factory calibrated for temperature.

Martini’s temperature probes are interchangeable and no temperature calibration is needed
when they are replaced.
If the temperature measurements are inaccurate, temperature recalibration should be per-
formed.
For an accurate recalibration, contact your dealer or the nearest Martini Customer Service
Center, or follow the instructions bellow.
• Prepare a vessel containing ice and water and another one containing hot water (at a

temperature of around 50 °C). Place insulation material around the vessels to minimize
temperature changes.

• Use a calibrated thermometer with a resolution of 0.1 °C as a reference thermometer.

• With the instrument off, press and hold down the CAL & LOG/MR keys, then power on the

instrument. The “CALIBRATION” tag will appear and the secondary LCD will show 0.0 °C.

• Immerse the temperature probe in the vessel with ice and water as near as possible to the

reference thermometer. Allow a few seconds for the probe to stabilize.

• Use the UP and DOWN arrow keys to set the reading on the secondary LCD to that of ice

and water, measured by the reference thermometer. When the reading is stable and close to
the selected calibration point, the “READY” and “ACCEPT” tags will blink.

• Press the GLP/ACCEPT key to accept the calibration point. The secondary LCD will show

50.0 

°

C.

• Immerse the temperature probe in the second vessel as near as possible to the reference

thermometer. Allow a few seconds for the probe to stabilize.

• Use the UP and DOWN arrow keys to set the reading on the secondary LCD to that of the

hot water, measured by the reference thermometer.

• When the reading is stable and close to the selected calibration point, the “READY” and

“ACCEPT” tags will blink.

• Press the GLP/ACCEPT key to accept the calibration point. The instrument returns to measure-

ment mode.

Note: If the reading is not close to the selected calibration point, “WRONG” tag will blink. Change

the temperature probe and restart calibration.
