Parameters
P643 External Contact Closure
Sets the duration of the contact closure, in ms, for the external totalizer selected,
totalizers 1 and 2 (P643-01 or -02). (
f
= 30)
Permissible values are in 10 ms increments from 0 to 300 ms. The value is automatically
calculated upon entry of P11 (design rate) and P638 (totalizer 1 resolution, external) so
that the duration of contact closure allows the transistor switch response to track the
total, up to 150% of the design rate. The value can be changed to suit specific contact
closure requirements, such as in the case of programmable logic controllers.
P647 Totalizer Display
Selects the totalizer combination to be displayed, either manually through the scroll
display key or automatically by control of the display mode (P081).
Entry:
1 = totalizer 1
f
2 = totalizer 2
3 = totalizer 1 and 2
P648 Totalizer Reset, Internal
Manual reset of the selected internal totalizer when the entry is made. (
f
= 0)
Entry:
0 = no reset
1 = reset totalizer 2
2 = reset totalizers 1 and 2
Resetting the internal totalizers 1 and 2 resets the internal registers for external totalizers
1 and 2.
P699 ECal mV Span
This parameter becomes available when Ecal is selected in P002.
Enter the mV span corresponding to 0 to 100% full scale rate. The display changes to P017
to show the design rate value as the test rate.
Note: If the duration selected causes the totalizer to lag behind the count
rate, the next possible duration is automatically entered.
