Calibration Total
(For all JOBs per CHANNEL)
Records the accumulated total of all material for all JOBs
through a CHANNEL while in CALI-BRATION MODE of
operation since last reset.
Grand Total
(For all JOBs per CHANNEL)
Records the accumulated total of all material for all JOBs
through a CHANNEL, including while in CALIBRATION
MODE of operation, since last reset. Any time period
associated with this total is based on when it is reset. For
example, if it is reset at the end of a shift, end of the day,
or end of the year.
Clean Total
(For all JOBs per CHANNEL)
Records the accumulated total of all material for all JOBs
through a CHANNEL, while in CLEAN MODE of operation,
since last reset. Any time period associated with this total
is based on when it is reset. For example, if it is reset at
the end of a shift, end of the day, or dend of the year.
CALIB PROC
CHANNEL #
CHANNEL to be calibrated (1-8). Each CHANNEL must
be calibrated separately.
Calibration Mode
Sets open-loop manual or closed-loop automatic calibra-
tion mode.
- Open-Loop or Manual Calibration Mode
This mode attempts to flow material at the highest flow
rate possible by setting the output to the E/P transducer
at the MVR HIGH parameter, located in the JOB table, for
the selected CHANNEL. No less than 200 cc of material
should be dispensed during calibration. Otherwise, the
error in calibration will be too large. With 200 cc of ma-
terial dispensed into a beaker, the error in calibration will
be limited to+/- 0.5%, since the measured volume can be
determined to only the nearest cc. The operator must open
and close the calibration valve, or supply a GUN TRIGGER.
The material volume is entered by the operator and a new
Pulses/Liter is calculated.
- Closed-Loop or Automatic Calibration Mode
This mode sets the flow rate set point for the selected
CHANNEL based on the Total Flow Rate and Ratio for
the selected GUN, as stored in the JOB, since calibration
should always be performed at the normal flow rate for the
CHANNEL. The Calibration Time is also set based on the
flow rate so that no less than 200 cc of material will be dis-
pensed during calibration. Otherwise, the error in calibration
will be too large. With 200 cc of material dispensed into a
beaker, the error in calibration will be limited to +/- 0.5%,
since the measured volume can be determined to only the
nearest cc. The operator may override both the Calibration
Time and Calibration Set Point, if desired. The operator
must open and close the calibration valve, or supply a GUN
TRIGGER. The material volume that passed through the
GUN is recorded. The measured volume is entered by
the operator and a new Pulses/Liter value is calculated.
Automatic calibration mode may not be selected for the
Master channel of a Manual Gun since it normally has no
MVR to control flow rate.
Calibration Time
Sets the time duration for calibration.
Flow Rate Set Point
Sets to actual flow rate during calibration. This value is
based on the Current Pulses/Liter parameter, so it will be
inaccurate if that parameter is inaccurate.
Actual Flow Rate
Displays the actual flow rate during calibration. This value
is based on the Current Pulses/Liter parameter, so it will
be inaccurate if that parameter is inaccurate.
Number of Pulses
Displays the actual number of pulses received from the
flow meter during calibration.
Calculated Volume
Displays the calculated volume of material that should be
in the beaker when the calibration is stopped. This value
is based on the Current Pulses/Liter parameter and the
Number of Pulses received, so it will be inaccurate if the
Current Pulses/Liter parameter is inaccurate.
Measured Volume
The measured volume (cc’s) of material in the calibration
beaker. This value is entered by the operator. Once a
non-zero value is entered, the operator may not enter a
Measured Weight and Specific Gravity.
Measured Weight
The measured weight of material (grams) in the calibration
beaker (less the tare weight of the beaker). This value is
entered by the operator. The scales used should be accurate
