Micro 800 Conductivity/TDS/Salinity Operating Instructions
• 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).
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.
Conductivity/TDS/Salinity Calibration
For best results, periodic calibration with known
accurate standards is recommended. Calibrate with
standard(s) near your intended measuring range.
Provide stirring for best results. After calibration, the
electrode efficiency that corresponds to the active
measurement will be visible on the bottom display. "- - -"
will be shown if no calibration is performed. Press
MEAS to return to measurement mode at any time.

Using Automatic Conductivity Recognition
1 From Conductivity measurement mode, dip
the sensor into your standard - either 84µS,
1413µS, 12.88mS, or 111.8mS, then press
CAL. The primary display will search for the
nearest standard. The secondary display will
show the un-adjusted value and the bottom
display will show the temperature. One
calibration value in each range is allowed.

2 When the READY indicator appears, press
ENTER to accept. The primary reading will
flash "DONE".
3 To calibrate another standard, rinse your
electrode(s) then dip into your the next standard
or press MEAS to return to measurement mode
at any time. 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 After the desired number of standards has
been calibrated, the bottom display will show
the efficiency in measurement mode.
Using Manual Adjustment
1 From Conductivity/TDS/SALINITY
measurement mode, dip the sensor
into your standard then press CAL.
2 When the READY indicator appears, use
up/down arrows to adjust the primary reading
to match the standard value at the measured
temperature, then press ENTER.
3 Rinse your electrode(s) then dip the sensor into
your next standard, or press MEAS to return
to measurement mode. Repeat as necessary.
After the desired number of standards have
been calibrated, the bottom display will show
the efficiency in measurement mode.
Temperature Calibration/
Manual ATC
Temperature calibration is recommended
prior to first use, after ATC sensor replacement,
and periodically as needed.
1 Press CAL from any measurement,
then press MODE.
2 Skip to step 3 for manual ATC, otherwise, dip
the temperature sensor into a solution with a
known accurate temperature. The upper display
shows the active temperature while the lower
display shows the factory default temperature
without adjustment.
3 Use up/down arrows to adjust the upper
display. Press ENTER to accept the calibration
temperature. The maximum adjustable value
is ±10ºC (or ±18ºF) from factory default.
