Problem
Suggested Course Of Action
Signal not showing the
correct amount of mA.
Check if J3 not set for voltage output.
Check if burden resistor not too high.
Signal supposed to give
2-10V, but is pinned high
above 10V.
Check if J3 not set for current output.
Signal output gives weird
response.
Signal output jumpy.
Check to “Sig From” and “Sig To” settings. Increase the
difference between the two points.
Increase difference between “From ppm” and “To ppm”.
Signal output does not
respond enough.
Check to “Sig From” and “Sig To” settings. Decrease the
difference between the two points.
Change the difference between “From ppm” and “To ppm”.
Current output jumper set
correctly but output is pinned
high.
Check the burden resistor of the monitor. Check cable to the
monitor.
The signal output is dropping
below 2mA and I am getting
a fault indication from the
monitor.
The 0-10V or 0-20mA mode is enabled. Go to the “JumperJ3”
menu item and select “RightMA”. Check the signal end-point
settings.
Check to see if the unit is not showing a fault condition.
