CALIBRATION OF ANALOG OUTPUT, CONT.
The analog output has been calibrated at the factory and should require no other adjustment.
If, for some reason, it is found necessary or desirable to readjust this output, the procedure
listed below may be used.
In order to calibrate the analog output, it is first necessary to enter the Calibration mode by
gaining access to the calibration switch. Refer to the Setup and Calibration section of the
indicator manual for additional information.
The following prompts apply only if the 2XX-DAC board is installed.
ANALOG OUTPUT - Analog Output Option
With the ANALOG OUTPUT prompt displayed, press the ENTER key. The display will change to
show LOW WT=.
LOW WT=
Press the ENTER key to show stored value. This is the value, in weight, which outputs zero
volts (or 4 mA) from the DAC. All weight below this target will output zero volts (or 4 mA). If
the setting is acceptable, press the ENTER key again to save it. Otherwise, using the numeric
keys enter the desired weight value, then press the ENTER key to save it. Note that the
NET/GROSS key is used to change the weight sign. For example, to input –1000 as the
weight value, press 1 0 0 0 NET. Allowable values are: -99999 to 999999.
HIGH WT=
Press the ENTER key to show the stored value. This is the value, in weight, which outputs the
maximum selected voltage and current (see VOLTS OUT=). All weights above this value will
output maximum volts from the analog output board. If the setting is acceptable, press the
ENTER key again to save it. Otherwise, using the numeric keys enter the desired weight
value, then press the ENTER key to save it. Allowable values are: 1 to 999999.
NOTE! This weight must be a positive value, up to the capacity of the scale, and above
the LOW WT= value.
VOLTS OUT=
Press the ENTER key to show the stored value. This is the maximum output value in volts
(00.01 to 10.00). All weight values equal to or greater than HIGH WT= will output this value.
Note, that if the scale displays CAPACITY (over capacity), this value is used also. If the setting is
acceptable, press the ENTER key again to save it. Otherwise, using the numeric keys enter
the desired, then press the ENTER key to save it. Allowable values are: 00.01 to 10.00.
NOTE! If the 4 to 20 mA current output is used, set VOLTS OUT= to:
Current=

VOLTS OUT=
