nIon Calibration (Ion 700 Only)
The available ION calibration values are 0.10, 1.0, 10.0, 100.0, and 1000 parts per million (ppm).
Choose a minimum of 2 consecutive values for calibration and prepare the corresponding ion
calibration solutions. For best results always begin with your lowest standard value, followed by
the next lowest standard.
1. Connect the ISE and press as needed to select ppm. Note: The primary reading will show
“- - - -” without a stored ion calibration. The secondary value is the corresponding mV reading
of the ISE.
2. Dip the ISE into your lowest standard solution value and stir. Press when the secondary
reading is stable.
3. Press or to match the primary display to your corresponding ion calibration
value (0.10, 1.0, 10, etc).
4. Press to accept or to abort. The primary display will show the next highest calibration
standard value.
5. Rinse the ISE then dip into the corresponding calibration standard and stir.
6. Press to accept or to cancel. The mV/decade slope value will be displayed briefly if the
calibration is successful. “SLP Err” indicates calibration for the current point was not successful.
7. Revert to step 3 to calibrate additional points or press as needed to return to measurement
mode at any time.

npH Calibration
For best results, periodic calibration with known accurate standards is recommended. The 700
series meters can be calibrated with up to 5 buffers. The non-volatile memory retains all calibration
values upon meter shut down.
The following calibration standards are automatically recognized;
To eliminate temperature errors associated with the pH electrode, attach the automatic
temperature compensation (ATC) probe for best accuracy.
1. Press as needed to select pH.
2. Dip the pH and ATC electrodes into pH buffer and press . The secondary display will lock on
the appropriate buffer value. Provide stirring for best results.
When the READY indicator appears, press to accept. The primary reading will flash briefly
before the secondary display begins scrolling the remaining available buffers.
3. Rinse the pH and ATC electrodes then dip into the next pH buffer. The secondary display will
lock on the appropriate buffer value. When the READY indicator appears, press to accept.
The primary reading will flash briefly then display the percent efficiency (slope) before the
secondary display begins scrolling the remaining available buffers.
4. To calibrate another buffer repeat step 3 or press to return to the measurement mode.
nTemperature Calibration
The thermistor sensor used for automatic temperature compensation and measurement is
both accurate and stable. Temperature calibration is recommended upon electrode
replacement, whenever the temperature reading is suspect, or if matching against a certified
thermometer is desired.
1. Connect the temperature probe to the meter and place into a solution with a known accurate
temperature such as a constant temperature bath.
Note: To adjust the manual temperature compensation (MTC) value, do not connect the
temperature probe.
2. Press as needed to select pH or mV/R.mV.
3. Press followed by . The primary display shows the measured temperature while the
secondary display shows the factory default temperature.
4. Adjust the temperature using or . Press to accept or to cancel. The meter
allows an adjustable maximum value of ± 5 ºC (or ± 0.9 ºF) from the factory default temperature.
nMillivolt (mV) Oset Adjustment
Oxidization Reduction Potential (ORP or Redox) is not a precise measurement, but is useful as a
relative indicator. mV offset adjustment makes readings comparable to a reference.
1. Connect an ORP electrode and press as needed to select mV (or R.mV).
2. Dip the ORP electrode into a solution with a known mV value and stir.
3. Press when the reading is stable. The primary display shows the relative millivolt value
(R.mV) while the secondary display shows the factory default mV value.
4. Adjust the R.mV value using or . Press to accept or to cancel.
The meter allows an adjustable maximum value of ± 150 mV from the factory default
mV value.
Note: When an offset has been stored successfully, R.mV replaces mV.
nMeter Connections
pH BNC connection for pH, ORP (Redox), or
Ion Selective Electrodes (ISE).
REF
Pin connection for half cell reference electrodes.
Requires separate half cell BNC electrode.
Note: REF is not commonly used and is not required.
