Programming the Instrument
Calculating a RATE and a TOTAL Factor
The value displayed for RATE is calculated as :
RATE = N x Scaling Value N = number of pulses counted in time T
T x FACTOR T = measurement time (usually 1 sec)
The value displayed for TOTAL is calculated as :
TOTAL = C x Scaling Value C = total count.
FACTOR
Programmable Parameters
The following values must be programmed into the unit in order to display the desired values:
i Factor
ii Total - scaling value
iii Total - decimal point position
iv Rate - scaling value
v Rate - decimal point position
Other parameters that may need to be programmed are:
vi Low Alarm limit
vii High alarm limit
And if the analogue output option has been specified:
viii Reference
ix Full Scale
In order to program the parameters the instrument must be operating in the SET mode. Unless the
appropriate parameters have been specified at the time of ordering, all values will be factory set to
zero when the instrument is first powered up.
Since zero is an invalid number for Factor or Scaling values, the instrument must have a link
connected between M0 (terminal 7) and 0V (terminal 9 Common), and will initially be forced into the
setup routine and will display
SET …. FACTOR …. 0 ( .... signifies a one second delay before the
display changes).
