Step 5. If the value does not exceed the maximum zero tolerance
value or is not a negative value, the screen will accept the new
value.
Step 6. If the value exceeds the maximum zero tolerance value or is a
negative number, an ERR 15 is displayed. You need to change
the value to meet the requirements in step "3". Go to step 4
and repeat steps 4, 5 & 6 to enter new values until the value
meets the requirements in Step 3.
Step 7. Press the Enter button to accept the new value. "AVRAGE"
sub-menu appears.
NOTE: Weight can accumulate up to the value entered for the Auto Zero Tolerance and the
instrument will automatically display a 0.
Setting the Number of
Readings Averaged
(AVRAGE) Step 1. This setting is to aid in ignoring the effects of material impact.
If material is not entering or exiting the scale evenly, neces-
sary weight fluctuations can be seen. Averages also contribute
50 ms each to the overall time to calculate the scale weight.
Applications requiring very quick weight readings should
reduce this setting to it's minimum. If the weight is unstable
due to material impacting, increase the averages. This sets the
number of weight readings that will be used to compute the
displayed weight. The average is a sliding average so that a
new average is available for display at every reading.
Step 2. This sets the number of weight readings which will be used to
compute the displayed weight.
Step 3. The average is a sliding average so that a new average is
available for display at every reading.
Step 4. The default number of readings per average is 10.
Step 5. Press the Enter button.
Step 6. Use the numeric keys to enter the new value in the range of 1
to 200. (If you enter a number greater than 200 or a negative
number, the ERR 3 statement will appear.) Press the -/Test/Clr
button. Enter a new number.
Step 7. Press the Enter button. The Scale Capacity (SC CAP) sub-
menu appears.
Setting the Scale
Capacity (SC CAP) Step 1. If this value is exceeded by 5% an HI indication appears on
the front display. Communications to and from optional
devices are not effected. This value is the nominal operating
capacity of the scale. The value you set should be the small
value between the capacity of the vessel (volume in Gallons
or Liters converted to weight in Lbs or Kgs) and the combined
weight capacity of the load cells (Lbs or Kgs).
Step 2. The value you set should be the smaller value between the
capacity of the vessel (volume in gallons or Liters converted
