To change the output signal's range, follow these steps:
- Remove the 2X sealing screws labeled Z and S to reveal the zero and span trim potentiometers.
- Extend the displacement cable to the desired start location and adjust the zero trim potentiometer until you get the desired electrical output.
- Extend the displacement cable to the desired finish location and adjust the span trim potentiometer until you get the desired electrical output.
- Repeat steps 2 and 3.
- Replace the 2X sealing screws.

A Note on Load Resistance in 4-20 mA Current Loops - The maximum load resistance or loop resistance is the maximum resistance of all the loads that are connected in series with the circuit. This includes all instrumentation equipment such as power supply and multimeter. The maximum load resistance (RLmax) depends on 2 factors: the voltage supply (Vps) and the maximum loop current (Iloop). For the Series 6 4-20 mA circuit, RLmax = (Vps - 11.6) / Iloop
Example:
Vps = 24 V
Iloop = 30 mA
RLmax = (24 - 11.6) / 30 = 0.413 Kohms |
To change the output signal's range, follow these steps:
- Remove the 2X sealing screws labeled Z and S to reveal the zero and span trim potentiometers.
- Extend the displacement cable to the desired start location and adjust the zero trim potentiometer until you get the desired electrical output.
- Extend the displacement cable to the desired finish location and adjust the span trim potentiometer until you get the desired electrical output.
- Repeat steps 2 and 3.
- Replace the 2X sealing screws.
