4.3 Analog CH1 to CH4 Setup
The 4 analog channels are universal analog input channels that can be used for pressure, temperature etc.
Only “CHANNEL 1” Setup is shown below, follow the same steps for Channel 2, 3 & 4
4.3.1 Pressure Setup
Mode:
Select the function for the analog channel. Options are “PRESSURE”, “TEMP” or “OFF”.
Type:
Select if you are using a resistive, voltage or current pressure sender.
If the
“RESISTIVE”
pressure sender is selected
In most cases resistive sensors require a biasing voltage to work properly. Inside the EMS3
unit is a small block of DIP switches, The switch associated with the required channel must be
in the ON position to enable the sensor to work correctly. By default, CH1 + CH2 are ON and
CH3 + CH4 are off. Failure to set the DIP switch will not cause damage but will cause false
readings.
