alibration operation
Measure standard solutions in ascending order of ion concentration to create
calibration curves in the meter (
“Ammonia electrodes” (page 54)).
Perform calibration once every day or before measurement as appropriate.
Before operation

Be sure to fill with internal solution and rinse the electrode
before the calibration operation. (
“Assembling the
electrode” (page 8), “Rinsing the electrode” (page 12))

Perform conditioning in the following cases:

Before the first use

Before use after storage for one week or longer

If the electrode is less responsive

After the replacement of the membrane cap

* ：
Prepare 5 mol/L aqueous solution of sodium hydroxide, or use
the pH-adjusting ionic strength adjuster (referred to as pH-
adjusting ISA in the rest of this document) available as consum-
ables. (
“Consumables” (page 41))
