2.7 Analog Output Connections
0 to 20/4 to 20 mA isolated or non-isolated
output as well as 0 to 5/0 to 10 VDC isolated or
non-isolated outputs are available. See section
4.4 for a list of available output cards.

3.1 Introduction
All the functions which can be modified are
contained in three menus:
The CAL (calibrate) menu contains those functions
which pertain to the input signal and how it is
interpreted by the instrument (i.e. K-factor, totalizer
reset). The CAL menu also provides access to the
security code and display contrast features.
The RELAY menu contains all the functions neces-
sary to control any output relays, such as relay
Note:
The maximum loop impedance for the 4 to 20 mA/0 to 20 mA output is 425
Ω
.
The minimum load impedance for the 0 to 5 V/0 to 10 V output is 1 k
Ω
(1000
Ω
). To
reduce the possibility of noise interference, separate output lines from AC power/relay lines.
