Summary of function
'CAL'
Calibration of the rate display
using an external current source.
Enables the zero and span of the
rate display to be adjusted using an
external current source such as a
calibrator. When used with an
accurate traceable calibrator this is
the preferred method of calibration.
See section 6.10
'5Et'
Calibration of rate display using
internal references.
Enables the zero and span of the
rate display to be adjusted without
the need for an accurate input
current or disconnection from the
4/20mA loop.
See section 6.11
‘Clr.Gtot’
Clear grand total
Resets the sixteen digit grand total
to zero when ‘Clr.YES’ is selected
and ‘5urE’ is entered digit by digit to
confirm the instruction.
Note:
Once cleared a grand total
can not be recovered.
See section 6.12
‘t-bA5E’
Timebase
Selectable divisor to display flow
rate in units per second, per minute
or per hour.
Select:
‘tb-01’
for flow / second
‘tb-60’
for flow / minute
‘tb-3600’
for flow / hour
See section 6.13
'C - - P'
Function of
P
push button
The Rate Totaliser may be
configured to display the input
current in milliamps, or the input
current as a percentage of the
4/20mA input when the
P
push
button is operated in the display
mode.
Select:
‘PC’
% of 4/20mA input
‘4-20’
Current in mA
Note:
‘PC’ is not available with
lineariser.
See section 6.14

Summary of function
‘5CALE-t’
Total scale factor
Defines the arithmetic relationship
between the rate and total displays.
May be adjusted between 0.0001
and 99999
5CALE-t = Units of rate display
Units of total display
To calculate 5CALE-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 6.15 and Fig 6.
'CLiP-oFF' Clip off
To prevent the totalisation of very
low flow rates, this function defines
the flow rate below which totalisation
is inhibited and the ‘HOLD’
annunciator activated.
See section 6.16
'LoC.r5Et' Local reset of total and grand
total.
Contains two independent functions
‘t-rE5et’ and ‘Gt-rE5Et’.
‘t-rE5Et’ enables the total display to
be reset to zero when ▼ and ▲
push buttons are operated
simultaneously for more than 2
seconds.
‘Gt-rE5Et’ enables the grand total to
be reset to zero when
E
and ▲ push
buttons are operated simultaneously
for more than 10 seconds.
See section 6.17
'CodE'
Security code
Defines a four digit numeric code
that must be entered to gain access
to the configuration menu. Default
code 0000 disables this security
function and allows unrestricted
access to all conditioning functions.
