For easy testing and adjustment, reference
signals are provided for the 2 output channels. For instance, by inserting a jumper plug, an
output can be forced to the full scale or zero level. A readout device can be easily
adjusted to comply with the transmitter output. Inside the transmitter box, there is a label
showing all the useful jumper combinations for output scale, measurement range, and
testing.

Verify the readings with the data collecting system at the receiving end.
-
To end the test stage, reattach the jumper J5 to the jumper
block X4.
-
After a successful test, carefully reattach the enclosure cover with the 4
screws.
| CAUTION Do not try to adjust the transmitter scaling from the sealed
potentiometers of the transmitter. |
