5.2.1.3 Analog Output Menu

Select using UP & DOWN buttons)
SSR-Ex allows the user to determine how an error message will affect

the analog outputs. Settings include driving the analog output either

to 0 mA, 2 mA, or 4 mA or the setting can be OFF to not affect the

output.
Default value is OFF.
SSR-Ex allows the analog output to be scaled to the desired range

using the 4 mA and 20 mA adjustments. Select either 4 mA or 20 mA

and using the UP & DOWN buttons adjust to the desired value.
Default values are 4 mA = 0 ppm and 20 mA = 15 ppm
The 4 and 20 mA outputs can be offset to account for signal loss

between the SSR-Ex and the SCADA system using the 4 mA and 20

mA CALIBRATE options.
