To access the settings below, press SETUP. Up/down
arrows will display the available options. Press
ENTER to accept the desired setting, or BACK
to return to the previous option and/or exit.
Configuration Options
• Ready indicator ON/OFF/
or Automatic HOLD when stable.
• Choose ºCelsius or ºFahrenheit.
pH Buffer Options
• Select the desired pH Buffer Calibration Group:
USA (1.68, 4.01, 7.00, 10.01, 12.45) or
NIST (1.68, 4.01, 6.86, 9.18, 12.45) or
DIN (1.09, 3.06, 4.65, 6.79, 9.23, 12.75) or
MAN (manual adjustment of any custom
pH values that are ≥1 pH unit apart.
• Select number of calibration points.
Select Calibration Due Reminder
• Set number of days from 0-60 for desired parameter.
View Calibration Data
• Press ENTER to view each point that is calibrated.
View Electrode Data
• Press ENTER to view mV Offset and
Slope % of the measured reading.
System Settings
• Data Logging:
MANUAL upon key press only TIMED interval.
Choose (SEC/MIN/HOUR) interval.
• Automatic shut off after 10 minutes.
Choose ON or OFF.
• Clock Settings:
Date: Choose USA (MM/DD/YYYY)
or Euro (DD/MM/YYYY).
Time: Choose (24HR or 12HR).
If 12HR, choose AM or PM.
• Set Printer Type:
CSV (Comma Separated Values) -
best format for computer.
Printer (Text) - best format for printer.
Choose Manual (MAN) upon
key press or TIMED interval.
If timed, choose (SEC/MIN/HOUR).
Digital Multiparameter Meter
Reset
• NO. Exits from reset menu options without action.
• FACTORY RESET. Returns all settings except
date/time and ATC calibration to factory default
values after ENTER is pressed then restarts meter.
• DATA RESET. Erases data stored in memory while
retaining other settings after ENTER is pressed.
• CALIBRATION RESET. Erases non-ATC
calibration data while retaining other settings
after ENTER is pressed.
pH Calibration
For best results, periodic calibration with known,
accurate standards is recommended. Calibrate with
standards that bracket your intended measuring
range while including a neutral standard (pH 7.00
or 6.86). For example, if you expect to measure
samples from pH 6.2 to pH 9.5, calibration with
4.01, 7.00, and 10.01 standards will work well.
Provide stirring for best results. After calibration with
two or more points, the active slope segment of the
measurement will be visible on the bottom display
during measurement. 100% slope will be shown if
only one calibration point is performed and "- - -"
if no calibration is performed. The meter will
automatically return to measurement mode upon
successful completion of the number of specified
calibration points. To specify a different number
of pH calibration points, see pH Buffer Options.
Using Automatic Buffer Recognition
1 While in pH measurement mode, dip the pH
and ATC sensor(s) into your first standard, then
press CAL. The primary display will search for
the nearest standard value, while the secondary
display will show the un-adjusted value.
2 When the "READY" indicator appears, press
ENTER to accept. The primary reading will
flash "DONE".
3 Rinse your electrode(s) then dip into the next pH
standard. The primary display will search for the
nearest standard value that has not yet been
calibrated, while the secondary display will show
the unadjusted value. When the "READY"
indicator appears, press ENTER to accept.
4 To calibrate another pH standard repeat Step 3 or
press MEAS to return to pH measurement mode.
