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.
- Replaced 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.
- Replaced the 2X sealing screws.

| Compatible Mounting Hardware |
A quantity of 3 self-tapping screws (roughly equivalent to No. 6 screws in size) are supplied for fixed mounting directly into the transducer housing in any 3 of the 6 mounting holes located on the transducer housing. These screws may be used to mount the sensor from the back side through panels up to 0.125 inch (3.175 mm) thick (recommended clearance-hole size in the mounting panel is .145 inch (3.683 mm) minimum). These screws are pre-installed on transducers with the mounting bases. The mounting holes and slots on the sensor are sized to accept alternative user-provided fasteners through the body up to No. 4 or 3 mm in size. See Technical Documents below for detailed information on installation options. |
