Instruction Manual Mi170 Bench Meter
• The temperature coefficient and compensation mode.
• The “dEL” message on the primary LCD and the record number on the secondary
LCD, along with “ACCEPT” tag blinking.
Notes:
• If one of the arrow keys is pressed while “dEL” message is displayed, the
next/previous record number will be selected.
• If the SETUP key is pressed, the secondary LCD will toggle between the record number
and “ALL” message.
• Press the GLP/ACCEPT key to delete the selected or all records.
• If “dEL ALL” option was selected, all records for the selected range are deleted and
the instrument returns to measurement mode.
• After deleting a record, the “nuLL” message is displayed on the LCD for the selected
record.
Press the SHIFT&LOG/MR keys to leave RECALL mode at any time.

Press the GLP/ACCEPT key to confirm calibration.
The instrument stores the calibration value and returns to measurement mode.
Notes:
• If the uncalibrated reading is too far from the expected value, the “WRONG” and
“SOLUTION” tags will blink. Calibration can not be confirmed. In this case check if
the correct calibration solution has been used.
• If the meter is in
ATC
mode and the solution temperature is out of the 0.0 to 60.0
°C (32.0 to 140.0 °F) interval, the “WRONG” “SOLUTION” “°C” tags and the
temperature will be displayed blinking.
• For best results choose an EC calibration solution value close to the sample to be
measured.
• It is possible to set the cell constant value directly, without following the calibration
procedure. To set the cell constant, enter SETUP mode and select “CEL” (see SETUP
for details, page 23).
NaCl CALIBRATION
NaCl calibration is a one-point procedure at 100.0% NaCl. Use the MA9066
calibration solution (sea water solution) as a 100% NaCl standard solution.
Rinse the probe with some of the calibration solution or deionized water. Immerse the
probe into the MA9066 solution. The sleeve holes must be completely submerged. Tap
the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.
To enter NaCl calibration select the NaCl range and press CAL.
The primary LCD will display the NaCl reading in percentage and the secondary LCD
will display “100”, along with “CALIBRATION” tag. The “WAIT” tag will blink until
the reading is stable.
