Lo - valley (min.) memory mode. If the valley memory mode is used and the remote input is set
to valley memory (Lo) then the alarm relay will be activated if the valley memory value is below
the low setpoint value. The alarm will not de-activate until the memory is reset.
dISP - display mode. If the live display mode is used then the alarms will operate purely on the
display value at the time i.e. if the display is showing above high setpoint or below the low setpoint
value then the alarm relay will activate.
5.44 Bargraph display operation mode
Display: bAR
Range: LiuE, tARE, P.HLd, d.HLd, Hi, Lo or dISP
Default Value: LiuE
The following choices are available for bargraph display mode:
LiuE - live input mode. The bargrpah display will always follow the electrical input at that time
irrespective of the 7 segment display value. For example if the remote input is set for peak hold
operation then when the remote input is closed the 7 segment display will only show the peak value
but the bargraph will be free to move up and down to follow the live input. Note that the LIUE
mode does not follow the electrical input if a remote input or P button ZERO operation has been
undertaken. This is due to the fact that the ZERO operation shifts the display calibration.
tARE - tare mode. The bargrpah display will follow the tare function i.e fall to zero when the
instrument is tared. If the remote input toggles the 7 segment display to show gross (GROS) then
the 7 segment display will change to show the gross value but the bargraph will not respond (see
LiuE for alternative operation.)
P.HLd - peak hold mode. The bargraph (and 7 segment display) will indicate the peak value
only whilst the peak value function is operated via a contact closure on the remote input i.e. the
bargraph and 7 segment display can rise but not fall whilst the remote input switch is closed.
When the remote input switch is opened the bargraph value will remain fixed i.e. it will not rise
or fall, although the 7 segment display value will be free to alter. This peak bargraph reading can
be cleared by closing the remote input switch for another operation or by temporarily removing
power from the instrument. Note: In this mode the bargraph will show a zero reading until the
remote input is operated for the first time after switch on.
d.HLd - display hold mode. The bargraph (and 7 segment display) value will be held whilst the
remote input display hold switch is closed. When the switch is opened the bargraph value will
remain fixed at the held value although the 7 segment display value will be free to alter. The held
bargraph reading can be cleared by closing the remote input switch for another operation or by
removing power from the instrument. Note: In this mode the bargraph will show a zero reading
until the remote input is operated for the first time after switch on.
Hi - peak (max.) memory mode. With the peak remote input switch open the bargraph will
indicate the peak value in memory i.e. the bargraph can rise but not fall. The bargraph can be
reset by clearing the memory. The memory may be cleared either by closing the remote input
switch for approximately 2 seconds or by temporarily removing power to the instrument.
Lo - valley (min.) memory mode. With the valley remote input switch open the bargraph will
indicate the valley (min.) value in memory i.e. the bargraph can fall but not rise. The bargraph
can be reset by clearing the memory. The memory may be cleared either by closing the remote
input switch for approximately 2 seconds or by temporarily removing power to the instrument.
dISP - display mode. The bargraph display will follow whatever value is on the 7 segment display.
