Operating Instructions, 12/2014, A5E03086491-AC
Resetting the Totalizer registers clears all total data accumulated during operation.
Note: In Dual Path mode, the Totalizer operates only on the virtual system channel
(Ch 3). Therefore in this case, the CLRTOT trigger would be <F3> <1>.
Commands that can be invoked from Si-Ware or HyperTerminal:
Terminal Command: CLRTOT 1.
Invoking the NOTOT command disables the Totalizer. Totalization will not resume
until you repeat the <Fn> <2> key sequence. When you activate NOTOT, an N pre-
cedes the TOTAL symbol (i.e. [NTOTAL]) on the LCD Screen.
Commands that can be invoked from Si-Ware or HyperTerminal:
Terminal Command: NOTOT 1 = Stop Totalizer
Terminal Command: NOTOT 1 = Start Totalizer
The LAPTOT command freezes the Totalizer screen display. However, the flow
meter will continue to update its internal registers. The flow meter will show the cur-
rent total when you repeat the <F1>< 3> key sequence. When you activate LAPTOT,
an L precedes the TOTAL symbol (i.e., [LTOTAL]) on the HyperTerminal screen.
Clears the Batch/Sample Totalizer register. The flow meter maintains a separate
Totalizer register for Batching or Sampling applications but cannot be accessed
directly. It is used for relay control only. If you assign the system relay to this func-
tion, a momentary (200 ms) relay pulse occurs whenever the BATCHTOT register
accumulates a specified liquid quantity. In the [Batch/Sample Tot] menu cell the
required total flow volume is entered to activate the relay,. This numeric entry must
reflect the selected flow total units. The [Totalizer Scale] menu cell shows the appli-
cable flow total units. The sign of the Batch/Sample Total determines positive or
negative accumulation.
Clears the Makeup Latch. Refer to the Span Data menu [Set Alarm Levels] and then
the [Makeup Latch] On / Off option.
