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.
ISE Calibration
The pH 450 can measure ion concentration such as ammonia or fl uoride
when using an ion selective electrode (ISE) for the specifi c ion of interest.
See Setup to select one of (3) ISE standard groups based on your intended
standards and range. Use a minimum of 2 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.
Refer to your Ion Selective Electrode instruction manual for details on
™
to attach one or more
conditioning, storage, maintenance, calibration standard preparation, Ionic
Strength Adjustment, trouble-shooting, etc. Each ISE is unique and requires
care and operation that is specifi c to the electrode and ion of interest.
1. Connect the ISE and press MODE as needed to view ppm. The primary
display will show "- - - -" without a stored ion calibration.
2. Rinse the ISE with clean water and dip into your lowest calibration
standard and stir. Press CAL.
3. Use t/s keys to match the primary display to your desired ion
calibration standard (0.10, 1.0, 10, etc). The secondary display is the
corresponding mV.
4. Press ENTER when the reading is stable to accept the calibration. ERR
indicates that the calibration for the current point was not successful.
This occurs when the slope (mV change between standards) is
<15 mV/decade or >90 mV/decade. The primary display will show the
next highest calibration standard. Use t/s keys to select a different
ion calibration standard if needed.
5. Rinse the ISE then dip into the corresponding calibration standard
and stir. Repeat Steps 3 & 4 as needed. If the number of calibration
points has been reached, the display will return to measurement mode.
Note: The mV/decade slope value will be displayed in during
measurement mode on the lower display upon a successful calibration.
The value corresponds to the slope of the active reading.
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.
• The calibration point was not successful. The allowable mV difference is
15 to 90 mV/decade.
• 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.
• Not intended for medical applications or patient use.
• WARNING: No modifi cation of this equipment is allowed.
