Analog Output Calibration Procedure
1. From the previous step in the Setup procedure press
UNITS >
CAL
is displayed.
2. Ideally you should directly connect the analog input device to the Analog Option card to calibrate the
analog output, but a digital multimeter can also be used to establish the initial calibration. Fine adjustments
can then be made when connected to the user instrument.
3. Press
SELECT >
ZERO
is displayed. Always perform the
ZERO
calibration prior to the
SPAN
adjustment
4. Use the following keys to adjust the analog output signal during the Zero and Span calibration
TARE
will add +0.1 %
SELECT
will subtract -0.1 %
will add +5.0 %
UNITS
will subtract -5.0 %
When setting the
ZERO
adjustment approach the analog zero setting from the positive side of zero
Example
: On a 4 to 20 mA adjustment, make the necessary adjustments until just slightly above 4.00 mA.
Then press the
SELECT
key until the external device indicates 4.00 mA. Do not press
SELECT
again as this
may cause non-linear readings at intermediate weight values
5. Press
ZERO >
ZERO
is displayed
6. Press
UNITS >
SPAN
is displayed
When setting the
SPAN
adjustment approach the analog span setting from the low side of span
Example
: On a 4 to 20 mA adjustment, make the necessary adjustments until just slightly below 20.00 mA.
Then press the
TARE
key until the external device indicates 20.00 mA. Do not press
TARE
again as this may
cause non-linear readings at intermediate weight values.
NOTE:
It is recommended to re-check the Zero
calibration setting if significant adjustments were made during the Span calibration to insure proper adjustment

The
LO
and

settings set the output range of
operation for the selected system parameter Initial
default settings:
LO = 0
and
HI = 5000
(default
capacity of the indicator)
13. Press
SELECT >
LO
is displayed
14. Press
SELECT
> previous value is displayed
Enter the minimum value where the analog output
signal range begins. Typically,
LO = 0
but any
value can be entered to set the starting point for
the minimum analog output signal
15. Press
ZERO >
LO
is displayed
16. Press
UNITS >
HI
is displayed
17. Press
SELECT
> previous value is displayed
Enter the maximum value where the analog
output signal range ends. Typically,
HI =
the
capacity of the scale but any value can be entered
to set the end point for the maximum analog
output signal.
