2.10.3 ANALOG INPUT SETUP (optional function)
The Analog Input Setup function assigns an active analog input to a measurement channel/path. The
meter provides four DC current input ports for single and Dual Channel units. The DC current input
ranges from a zero level of 4 mA to a full scale of 20 mA. The [Analog Input Setup] menu cell allows you
to enable this port and then span it to any desired scaling.
For example, when using the analog input viscosity function the numeric variables might be spanned
as follows: 4mA=1 (water) and 20mA=100 (more viscous liquid). This spanning configuration allows
the meter to use this constant numerical change to improve calibration in real time. The various flow-
meter models allow you to associate the analog input to active system variables such as specific
gravity, viscosity and others (see table on next page).
NOTE: Using the <F1> key (Totalizer clear command) also clears all channel totalizers plus
the overflow register described in the last paragraph.
Assigning Relay 1 and 2 Functions
System 1010N, depending on the model, provides at least two alarm relays. Please refer to the Hard-
ware Installation Drawing for wiring details. Relays respond to any of the alarm conditions/data func-
tions included on the Relay Option List.
