Basic vs
Standard
pH mode
For optimum pH measurements, follow these steps:
1. Understand the benefits and features of Standard and Basic Operation.
2. Set up edge™ meter by configuring preferences.
3. Calibration
4. Measurement
The “Standard” pH operation includes up to a 5-point buffer calibration, use
of custom buffers, choice of displaying 0.001 pH resolution, use of the full
diagnostic features of Calibration Check™ (that includes buffers used, probe
condition, response time and messages indicating a contaminated buffer
or pH sensor requiring maintenance during calibration). Additional Sensor
Check™ indicators are available if using HI 11311 or HI 12301 pH electrodes.
These include a continuous diagnostic to detect if the electrode is broken
or the reference junction has been compromised by sample contamination
or fouling. The Standard pH operation also includes full logging capability
including Interval, Manual log on demand and Manual log on stability.
“Basic” pH operation provides a simplified SETUP menu; there are no decisions
to make regarding the pH measurement itself. The meter will display 0.01
pH resolution and permit a 3-point buffer calibration from the following
pH buffers; 4.01, 6.86, 7.01, 9.18 or 10.01. Calibration Check™ and Sensor
Check™ features are limited to messages during calibration. Calibration
reminders are also not available. The GLP will still provide offset, slope,
buffers used and a calibration date. The Basic pH operation includes Manual
log on demand and Manual log on stability (medium setting).
Note
: When changing from Standard to Basic operation in SETUP, previous
calibration data will be cleared. A prompt will force the user to facilitate this.
