mV CALIBRATION (for technical personnel only)

Mi 160 is factory calibrated for mV.
Martini’s ORP electrodes are interchangeable and no mV calibration is needed when they are
replaced.
If the mV measurements are inaccurate, mV recalibration should be performed.
For an accurate recalibration, contact your dealer or the nearest Martini Customer Service
Center, or follow the instructions below.
A two or three-point calibration can be performed at 0.0 mV, 600.0 mV and 1800.0 mV.
• Attach to the BNC connector a mV simulator with an accuracy of ±0.1 mV.
• With the instrument off, press and hold the CAL & GLP/ACCEPT keys, then power on the
instrument. The “CALIBRATION” tag will appear, and the secondary LCD will show 0.0 mV.
• Set 0.0 mV on the simulator.
• 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 display
600 mV.
• Set 600.0 mV on the simulator.
• 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 display
1800 mV.
• Set 1800.0 mV on the simulator.
• 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
measurement mode.

Notes:
•If the reading is not close to the selected calibration point, “WRONG” tag will blink. Verify
calibration condition or contact your vendor if you cannot calibrate.
•To exit the calibration mode press the CAL key in any moment and the instrument will return to
measurement mode. If you exit calibration after 600 mV is confirmed, the 600 mV range is
calibrated and calibration parameters are memorized.
