Place the scale in the desired position. Level the platform by adjusting the
four corner feet until the bubble in the bubble level, located beneath the top
platter of the platform is within the center circle. After a level condition is
achieved, test for a stable condition by trying to rock the platform backward
and forward and side to side. Adjust the feet beneath the indicator column
for final levelness and stability.
4200RSS:
The indicator box must be mounted to a vertical surface using the mounting
flanges on the top and bottom of the case. Access to the internal wiring is
accomplished by loosening the front cover latch screws and swinging the
front cover open.
4200M:
Locate the desired position for the scale indicator. If the indicator is to be
permanently mounted to a wall, shelf, or counter, remove the mounting
bracket from the indicator. Use the two holes provided in the bracket to affix
it to the desired surface. Before mounting the indicator into the bracket,
connect the scale platform and any data or communications cables to the
indicator. Insert one of the threaded studs into one of the mounting holes on
the bracket. Now gently spread the sides of the bracket apart and insert the
other stud into the hole on the opposite side. Loosely thread the two knobs
back onto the studs. Adjust the indicator to the desired viewing angle and
tighten down the knobs.
When choosing a location for the weighing platform, keep in mind that it should be on a
sturdy surface that is free from vibration and air currents. Vibration from heavy equipment
or appliances and air currents from fans, heating ducts, etc. can cause bounce on the scale
display. Using the Model 4200's Digital Averaging feature to minimize these effects is
outlined in Section 6 of this manual.
ELECTRICAL CONNECTIONS
The Model 4200 requires 120 VAC, 50/60 Hz power (240 VAC or DC power optional). Be
sure the AC power is not excessively noisy - this can occur if large inductive loads, such as
solenoids or motors, are on the same power line. The Model 4200 has a filtered power
supply to reduce the effects of normal line noise, but it cannot limit severe fluctuations. If
problems occur, noise producing devices may have to be suppressed to minimize their
effect.
Note - the AC power main disconnect is the power plug. To remove power from the scale,
simply pull the power plug.
