Orp Linear Transmitter (Ma) Output - JENCO 6309 POT Operation Manual

D. ORP LINEAR (mA) OUTPUT
The analog output will produce a linear analog output if the user
selects this option (see figure 2). The analog output will be
dependent on the ORP_4 mA setting, ORP_20 mA setting and the
current ORP (ABS or REL) display.
The ORP LINEAR output is based on the following equation:
mA = 4mA+(16mA)*(D
(ORP)
Where :
mA = analog output
(ORP)
D = current ORP (ABS or REL) display
(ORP)
ORP(4) = ORP(ABS or REL) user setting for 4 mA
ORP(20) = ORP (ABS or REL) user setting for 20 mA.
Note :
1. The user can set the 4mA and 20mA OUT from -9999 to 9999
AmV or -9999 to 9999 RmV, but be reminded that the range of
ORP in absolute mode is –2500 to +2500 AmV only, while in
relative ORP mode it's –6499 to +6499 RmV only.
2. The absolute difference of the 4mA and 20 mA settings must be
greater or equal to 10 AmV or 10 RmV or else the analog output will
be disabled.
