1. Make sure a probe is connected to the meter.
2. Push and select ISEF121 Settings.
3. Select Modify Current Settings.
4. Select Measurement Options and update the settings:
Option Description
Units Sets the preferred unit for ISE measurements—mg/L (default), µg/L, g/L,
g/kg, mol/L, mmol/L, mol/kg, %, ppm or ppb.
Note: The mV units are shown when the detailed display is selected.
Significant Digits Sets the significant digits shown—2, 3 (default) or 4.
Auto
Stabilization Sets auto stabilization—on (default) or off.
The default stability drift rate is 1.0 mV/min.
Stability Criteria When Auto Stabilization is off, sets the stability criteria—0.1 to
9.9 mV/min.
• Lower stability criteria will require longer stabilization times, but the
measurement will be more precise.
• Higher stability criteria will require shorter stabilization times, but the
measurements may be less precise.
• Stability criteria for factory-set methods: Pure water (0.2 mV/min),
Drinking water (0.4 mV/min); Default (1.0 mV/min).
Measurement
Limits Sets the measurement limits—Lower limit (default: 0.01 mg/L) or Upper
limit (default: 19,000 mg/L).
The measurement limits can be set to match the acceptable values for
the sample. When the measurement is above the upper limit setting or
below the lower limit setting, the meter shows an "Out of limits" message.
This message is an alert to a potential problem with the process
conditions.
5. If prompted, enter a name for the new method settings. Additional changes made to
the settings of an existing method are automatically saved with the same method
name.
6. Push EXIT until the meter returns to the measurement mode.
