Meter Preparation Prior to Calibration
Switching the Meter On and Off:
Press the
ON/OFF
key to power the meter on. All the LCD segments will be displayed for a
few seconds and then the display switches to the last measurement mode. To power the
meter off, press the
ON/OFF
key again.
Selecting the Measure Mode:
The measurement modes available are pH, mV, R.mV (for ORP) and temperature. Select
the correct mode of operation by pressing the
MODE
key and each key press toggles to the
next measurement mode. When selecting a particular parameter, the respective mode icon
is shown at the right hand side of primary display; these include “pH” for pH, “°C” for
temperature and “mV” for millivolt.
Meter Reset:
On first use, it is not necessary to reset the meter before calibration. To reset the meter to
factory default, refer to the Meter Setup Functions section.
Note:
After the meter is reset, a re-calibration is required before measurement. Likewise, to
prepare a new set of measurements, all the last calibrated pH values can be reset
simultaneously for added convenience.
Caution:
All calibration values and memory data will be erased upon meter reset and
calibration is required.
Selecting pH Buffer Standard:
The meter is capable of automatically recognizing either USA or NIST pH buffer standards.
Refer to Meter Setup Functions for details on how to change the USA buffer standard to the
NIST standard on the meter.
