and OD4 (continued)
5.0: Setting up the Transducer and OD4 (continued)
5.2: Basic Procedure (continued)
Null the transducer.
1. Replace the Gain link to the original position.
2. Adjust the position of the transducer to give as
near
to zero output as practical.
This is the centre of the mechanical range.
If the transducer cannot be centered for practical
reasons an offset will remain within the system.
There may be noticeable interaction between Gain
and Offset adjustment. This does not prevent the
OD4 being set-up. However several iterations
may be required when adjusting Gain and Offset.
Please contact your supplier if guidance is
required.
STEP 3 - Setting Bi-Polar Full-scale Output
1. Move the transducer to the position where
maximum OD4 output is required.
2. If the polarity of the output is wrong, move the
Polarity (FR) links to the R position (see link
diagram).
Move the transducer back and re-check the zero
position. Adjust transducer position as required.
3. Move the RANGE link between 1 and 6 until the
OD4 output is near the required value.
4. Adjust the Fine Gain control to give the required
output.
5. A bi-polar output has now been set, proceed to
step 5. If a uni-polar output is required, proceed
to step 4.
