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.
Using Manual Recognition / Custom Buffers
(450 Series Only)
1. While in pH measurement mode, dip the pH and ATC
sensor(s) into your first 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 repeat Step 2 with a standard
that is ≥1 pH unit from the previous standard value.
4. To calibrate another pH standard, repeat Step 3 or press
MEAS to return to pH measurement mode.
Part of Thermo Fisher Scientific
mV Offset Adjustment
1. While in mV measurement mode, dip the ORP and ATC
sensors into a solution with a known mV value (i.e. Zobel,
Light's, quinhydrone, or iodide/triiodide) and stir.
2. When the "READY" indicator appears, use up/down arrows
to adjust the primary reading to match the mV value at
the measured temperature, then press ENTER. The meter
allows an adjustable maximum value of ±200 mV from the
factory default mV value. When an offset has been stored
successfully, R.mV replaces mV.
Temperature Calibration/Manual ATC
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 ±10 ºC (or ±18 ºF) from factory default.
Error Messages
"ERR" will appear when an error condition exists or the
incorrect key is pressed. Common examples include:
• Pressing ENTER during calibration before the "READY"
indicator appears. Wait for the "READY" indicator before
pressing ENTER.
• UR (Under Range) • OR (Over Range)
Intended Use, Maintenance & Precautions
These handheld meters use sensors to detect various parameters
for water-based measurements. For routine maintenance
disconnect the power cord or battery, then dust or wipe the
display using a damp cloth. If necessary, warm water or a mild
water based detergent can be used. Immediately remove any
spilled substance from contact with the meter using the proper
cleaning procedure for the type of spill.
• Do not use this equipment in potentially explosive atmospheres.
• Refer to the electrode instructions for use, storage and cleaning.
• Ensure that no liquid enters the instrument.
• Do not use any aggressive cleaning chemicals (solvents or
similar agents).
• There are no user serviceable parts inside. Attempts to
service internal parts may void the warranty.
• WARNING: No modification of this equipment is allowed.
