Note:

When using custom buffers, CUST1 and CUST2 tags are displayed. If only one

custom buffer is used, CUST1 is displayed together with its value.

Expired Calibration

The instrument has a real time clock (RTC) to monitor the time elapsed since the last pH

calibration.
The RTC is reset every time the instrument is calibrated and the “expired calibration”

status is triggered when the meter detects calibration time out. The “CAL EXPIRED” warns

the user that the instrument should be recalibrated.

If the instrument is not calibrated or calibration has been deleted, the “NO CAL” message

is displayed.
Calibration time-out function can be set from 1 to 7 days (default) or off. See Setup section

Calibration Expired Warning for details.
For example, if the warning has been set to 4 days, the instrument will issue the alarm

4 days after the last calibration.
