Step 4. Press on the up or down arrow buttons to select the
display you want to see.
Step 5. With the cursor in front of mV and Weight, Press
the Enter button. The mV and Weight display
appears. (See Fig. 7-74)
FIG. 7-74 MILLIVOL.T AND WEIGHT READING
•
The mV and Weight is a coarser reading
than the mV/V and Weight. The reading is
sufficient to balance the corners of your
scale.
•
This reading allows you to determine if the
problem is in the instrument (internal) or
in a load sensor(s) (external). The specifi-
cation range for the Filler/Dispenser is 0-
15 mV. If you are getting a reading outside
this range the problem is probably the load
cell (electrical). If you are getting a read-
ing between 0-15 mV the reading is nor-
mal.
Step 6. Press the Exit button to return to the Choose Dis-
play screen.
Step 7. Press the up or down arrow buttons until the cursor
is in front of mV/V and Weight.
Step 8. Press the Enter button. The mV/V and Weight Dis-
play appears. (See Fig. 7-75)
FIG. 7-75 MILLIVOLT/VOLT AND WEIGHT READ-
ING
•
This reading is a higher resolution reading
to a 10th of a microvolt. Use this reading
to determine if the load cell is working
correctly.
•
You can also use this reading to determine
which load sensor is malfunctioning by
looking at each load sensor to determine
any problems (e.g. creep) in the millivolt
reading. Multiply the mV/V reading by the
sense voltage to get a mV reading with 3
decimals points.
•
Converting mV/V to mV use this formula:
5 x mV/V = mV
