An alarm time-out is available to alert the user if too much time has
elapsed since the last pH calibration and that re-calibration may be
required.
The meters provide a controlled access to calibration and GLP settings
through a password protection method.
The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weaker.
To prolong battery life, the backlight and printing features are
disabled when the batteries are getting low; "LOBAT" indication is
displayed on LCD to warn the user of this condition. However, the
meter continues to measure correctly even when the low battery
indication is displayed. The meter automatically switches itself off
when the batteries are too weak to support proper function.
The meters are equipped with an internal lithium battery that
powers the clock circuit even in the absence of power supplies.
For long term field and lab applications, these meters can be connected
to a 12VDC adapter.
When in logging mode,

When in logging mode,
the meter stores the measurements in memory
at a user selectable interval from 1 to 180 minutes. This information can
be retrieved at a later time and also printed.
