3. When the reading is stable and close to the selected standard, the READY and ACCEPT
tags are displayed blinking. Press GLP/ACCEPT to confirm calibration.
For one-point calibration, press CAL to exit calibration. The instrument stores the
calibration and returns to Measurement mode.
To continue calibrating, rinse and place the probe tip approximately 4 cm (1 ½”) into the
next solution and stir gently. If needed, press the
keys to select a different value.
Note:
The instrument will automatically skip the standard used for the first point.
Press RANGE to display temperature reading during calibration.
Notes:
The slope window is within ±20 mV and ±105 mV if ion charge is not specified (UndF
option in Setup menu), or between 50% and 120% of default slope for the corresponding
ion charge.
Default slope values (mV/decade):
– 59.16 (monovalent anion) - ion charge is –1
59.16 (monovalent cation) - ion charge is 1
– 29.58 (divalent anion) - ion charge is –2
29.58 (divalent cation) - ion charge is 2
100 - ion charge is “UndF”
If a one-point calibration is performed after a two-point calibration, the instrument
keeps the old slope.
