7.6.5.4 SAMPLE INITIATION using 4-20mA Input
The following sequence of entries are made
on the Touchpad to form a basic operating
parameter for operation of the sampler. This
will determine the number of pulses from
the start of a sample cycle to the start of the
next sample cycle. The ACTIVE
SETTINGS are not being altered.
1. Press the SET key.
2. Press the SAMPLE INITIATION key
3. Press an ARROW key. Continue until 4-
20mA Input is shown on the display.
4. Press the ENTER key.
The display will show a new screen
containing the option title 4-20mA INPUT
on the top line and a 7 digit number with the
leftmost digit flashing as a prompt for input.
The 4-20mA input will be converted by the
controller to pulses, proportional to the span
of the input, at the rate set in the
specifications. To set the number of pulses
required to be input before a sample is taken,
use the ARROW keys to move the flashing
prompt until it is over the digit requiring
change.
Press a number key (0-9) to replace any
existing number and advance the flashing
prompt to the next digit to change. Replace
digits as required, then press ENTER.
