Cal Reminder Audible Alarm
When the cal reminder interval has elapsed a visual warning is displayed in place of
the relevant reading, to enhance this warning an audible alarm that bleeps every 5
seconds can also be enabled. This audible warning is active whenever the
conductivity tab on the menu bar is selected. To enable the audible alarm, press the
down arrow to highlight the Cal Reminder Audible Alarm option on the Cal Reminder
sub-menu, then press the Enter key. The current selection is highlighted and the up
or down arrow keys can be used to toggle between the enabled and disabled options.
Press the Enter key to accept the desired setting when it is highlighted on the display.
Use the Escape [ESC] key to move to other menu levels or return to the main
measurement screen.
4.20 Conductivity Alarms Set Up
Two alarm levels are available for each mode of operation. One is a HIGH level with
the alarm being tripped when the measured value goes ABOVE the high level
entered. The other is a LOW level with the alarm being tripped when the measured
value goes BELOW the low level entered.
With the alarm function enabled a visible indication is given, when the alarms are
tripped, via the alarm bell icon on the display with an upward pointing arrow when the
Conductivity High Alarm indicated by alarm bell icon and upward arrow
high alarm is tripped and downward pointing arrow when the low alarm is tripped. It is
also possible to enable an internal audible alarm to complement the alarm bell icon.
An output from the rear panel sockets is also available to switch external audio/visual
alarms or for simple control/telemetry functions via external relays. Details of the
relevant connections for these outputs are contained in Section 10.6.
