8.2.6 Reagents Monitor
REAGENTS MONITOR YES 
When REAGENTS MONITOR is activated (YES by default), the
system creates a new Reagent Status screen which displays the
amount of reagents and the estimated number of days left for
each reagent to last. The Reagent Status screen is displayed for
a period of 15 minutes and the system automatically reverts
back to the default Reaction Result screen.

BioTector calculates the reagent usage and the days remaining
based on the average reagent usage from the reaction archive.
If there are no reactions available in the archive, BioTector
calculates the reagent usage using the operation range
information in the system program menus and updates the
reagent status figures accordingly.

Note that when one or more reagent volumes are updated in this
menu, system automatically resets the new reagents volumes in
Install New Reagents menu and also updates the figures
displayed in the main Reagents Status screen.
LOW REAGENTS NOTE

LOW REAGENTS, which is programmed as NOTE (notification)
by default, will activate a relay specifically programmed for
notification events.

When LOW REAGENTS is programmed as WARNING, and if
reagents run low, system generates an “85_LOW REAGENTS”
warning and activates a relay specifically programmed for
warning events.
LOW REAGENTS AT 5 DAYS

LOW REAGENTS AT specifies the number of days (5 days by
default), before the system generates an “85_LOW REAGENTS”
warning or notification, depending on the LOW REAGENT
setting above.

This function can be used by the user as an early warning or
notification of system low reagents so that the required reagents
can be prepared or ordered in time.
NO REAGENTS WARNING

NO REAGENTS programmed as a WARNING event by default,
can also be set as a FAULT event. When system calculates no
reagents, the fault relay is activated and system generates a
“20_NO REAGENTS” fault or warning.

NO REAGENTS can also be programmed as NOTE
(notification) where only a relay programmed as notification
operates in the event of no reagents.
ACID VOLUME 19.0l ~46 DAYS 
ACID VOLUME allows the user to enter the volume of the acid
reagent. When the volume is programmed, system automatically
calculates the number of days acid reagent will last.
BASE VOLUME 19.0l ~46 DAYS

BASE VOLUME allows the user to enter the volume of the base
reagent. When the volume is programmed, system automatically
calculates the number of days base reagent will last.

It is strongly recommended that each time acid and/or base
reagents are replaced or topped up, a Zero Calibration cycle is
activated using the Start New Reagent Cycle function in Install
New Reagents menu or using the Run Zero Calibration function
in Zero Calibration menu.
