Calculate Pulse Input Frequency
the example contained in Figure 113 on page
a technician can calculate the Pulse Input Fre-
quency required to effectively calibrate the NJEX
System.
If the pulse input frequency is between 1-1000 pulses
per second (Hz), choose PPS,
figure 110
.
-OR-
If the pulse input frequency is between 1-100 pulses
per minute, choose PPM,
figure 110
.
Span Adjustment
, is used to calibrate the N-300G
controller for 100% of metered flow at maximum input
frequency, i.e. 100 pulses per second at maximum
gas flow.
To set the span adjustment
,
figure 111
& 112,
press
and release the
Select
key. The value entry will
begin to flash when it is chosen. Use the
Up Arrow
key to increase the value and the
Down Arrow
key
to decrease the value. When a new value has been
chosen press the
Enter
key to store the value into
memory. The value entry will stop flashing when
loaded into the memory.
