6.0 CONFIGURATION
All ADTECH units are factory calibrated per P.O. instructions.
Usually, a complete recalibration is not required uf'lless you want to
change input type, output type, or the range of the unit. A calibration
sticker located on the unit identifies the model, calibration and
options present.
NOTE: For recalibration to the existing range proceed to section 6.1;
for new input or output range proceed as follows.
A.
Remove the right cover to expose the 8 position switch and
Jumper J1 on the input PCB Oust obove the potentiometers).
B.
Set output configuration jumpers per table 1 in section 8.0.
C.
Set switch 3 position 1 for upscale or downscale burnout. Set
switch 3 position 2 to Linearized or non-linearized per table 2,
section 8.0.
D. Set switch 3 position 3 to the on position and adjust the output
zero potentiometer for the proper output.
Set switch 3 position 3 to off and position 4 to on. Adjust the
E.
output span potentiometer for full scale output. Repeat steps
D and E until you reach the desired accuracy. (Note: you can
check the midscale value by depressing switch 3 positions 3
and 4 simultaneously.)
F.
Return switch 3 positions 3 and 4 to the off position, and
proceed with section 6.1 below to finish the calibration.
6.1
CALIBRATION
A.
Apply the zero input value at the input terminals of the unit.
Depress and hold the Zero input calibration push button switch
until the Zero status led flashes. You have just set the input
zero, and the output should be at your zero value after a short
time delay.
B.
Apply the full scale input value at the input terminals. Depress
and hold the Span input calibration push button switch until the
Span status led flashes. You have just set the full scale value
and the output should be at full scale after a short delay.
C.
Calibration is complete. Check the calibration with various input
values and verify the output values.

The instrument is made of small components. Troubleshooting
beyond the above may be difficult with out special equipment. We
do not recommend attempting repair of he unit in the field. ADTE CH
offers a very responsive repair policy. Contact the ADTE CH factory
for information on repair and return at 716-383-8280 or 716-383-

CORRECTIVE ACTION
Check the input and output
connections carefully.
Check that the power supply polarity
is correct and that the output loop
power is present on the indicated
terminals.
Check that the input source(s) is
correct and that it changes magnitude
between zero and full scale values
when so adjusted.
Make sure the output loop is
complete and that the correct meter
range is selected.
All external checks are complete.
Problem seems to be internal.
