P20 is used to view the pH electrode data (slope value) and used this data to judge the
availability of p H probe.
1. Enter setup mode, press
△
or
▽
key to enter the ELE P20 (Fig 4) display.
2. Press ENTER to view P22, the slope value will be displayed on LCD, same as
P23 (Fig 5). As maximum 3 PH calibration points is allowed in this meter so the
user can review two slopes value. If the value is <75% or > 115%, it is suggested
to change electrode immediately.
P30 is used to review the previous conductivity calibration data at different range.
1. Enter to setup mode and press
△
or
▽
key in the setup mode to check the CAL
P30 calibration message. (Fig 6)
2. Press ENTER key, to enter the calibration information screen with P32 . P33.
P34. P35 CON. uS or mS calibration information. (Fig 7)
3. P32 will display calibration information in Range 1. P33 will display calibration
information in Range 2. ---P35 will display calibration information in Range 4.
4. Press ENTER key to return to CAL 30 screen. (Fig 6)
