Description of function
'Cond'
Indicator conditioning
This is a protected sub-menu which
contains the calibration routine for the
two internal references 'rEF', and the
mains (line) frequency filtering
function 'FrE'.
See section 6.9
CAUTION
Please read sections 6.9 and
6.9.1 of this manual before
changing any of the
parameters in this sub-menu.
Incorrect adjustment may
result in reading errors.
'CLr. Gtot' Clear grand total
This function resets the grand total to
zero when 'CLr YES' is selected, and
'SurE' is entered to confirm the
instruction.
Note:
Once cleared, a grand total can
not be recovered.
See section 6.10
't-bASE'
Timebase
Three selectable divisors which
define whether the rate display
represents flow per second, per
minute or per hour.
See section 6.11 & Fig 6.
‘C - - P'
Function of P push-button in
display mode
The instrument may be programmed
to show on the rate display the input
current in milliamps, or the input as a
percentage when the
P
push-button
is operated in the display mode.
Select ‘PC’ for % of span and 4-20 to
display current.

Description of function
'SCALE-T' Total Scale Factor
Defines the arithmetic relationship
between the rate and total displays.
May be adjusted between 0.0001 and
65535
SCALE-t = Units of rate display
Units of total display
To calculate SCALE-t the required
units of measurement for the total
display must be converted to the units
of measurement used for the rate
display.
See section 6.13, 7 and Fig 6.
'CLIP-OFF' Percentage Clip off
To prevent totalisation at very low
flow rates, this function enables the
user to select a percentage rate
below which the rate display is
forced to zero. Adjustable between
0 and 10% of flow for linear inputs,
and 5 to 10% when the root function
is used to linearise a square law
input.
See section 6.14
'LOC.rSEt' Local reset of total display
When turned 'On' this function
enables the total display to be reset
to zero by simultaneously operating
the
Up
and
Down
push-buttons.
See section 6.15
'COdE'
Security code
Defines a four digit numeric code
which must be entered to gain
access to programmable functions.
Default code 0000 disables the
security function and allows
unrestricted access to all
programmable functions.
See section 6.16
