(CAL 1) AUTOCALIBRATION - Using 9000-INT Motorized Internal Calibration Weight
NOTE: Dual range models must be placed in HI range before starting the calibration procedure.
NOTE: For correct calibration weight refer to specification charts on pages 28-31.
The balance should be warmed up for at least one (1) hour prior to calibration and leveled according to the Unpacking
and Setup section. Perform autocalibration every time you move your balance.
CAL 1 Using the Internal Weight (This procedure calibrates your balance to the internal weight)
1. Remove any containers or weighing samples so
that nothing is on the stainless steel pan. Then
press the ZERO switch.
0.0000 is displayed.
2. Press the FUNCTION switch (or MODE and
RANGE switches simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T ,
and CAL 100.
3. Press the MODE switch when CAL1 appears. CAL1 and a flashing 0 are displayed.
4. Wait 10 seconds. Then press the MODE
switch.
The display shows a flashing CAL. This means that the automatic
calibration procedure using the internal weight has begun. The
procedure will take about 30 to 90 seconds. When the procedure is
complete, the display will blank and then return to its normal
weighing mode. This means that your balance is now calibrated. If
the calibration cannot be completed due to air currents, an unstable
environment (vibration), an incorrect weight, or any other reason; a
brief “ERR” message will appear on the display and the balance will
return to Step 3.
CAL 1 Using an External Weight (This procedure calibrates your balance to the external weight and then calibrates the
internal weight to the external weight)
1. Remove any containers or weighing samples so
that nothing is on the stainless steel pan. Then
press the ZERO switch.
0.0000 is displayed.
2. Press the FUNCTION switch (or MODE and
RANGE switches simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T ,
and CAL 100.
3. Press the MODE switch when CAL1 appears. CAL1 and a flashing 0 are displayed.
4. Wait 10 seconds. Then press the ZERO
switch.
The display stops flashing. In about 10 seconds, either a single weight
value or two alternating weight values will flash on the display.
5. Place one of the flashing calibration weights on
the pan.
The display stops flashing and the selected weight is displayed. If Err
1 appears, the calibration weight is an incorrect weight. Remove the
weight and use a proper weight. If Err 2 appears, the balance is not
warm enough for calibration. Wait one hour before starting the
calibration procedure again.
6. Wait 10 seconds. Then press the ZERO
switch.
The weight continues to be displayed while the calibration takes place
(about 10 seconds). Then the display blanks, displays “OK” for one
second, then shows CAL1 and a flashing 0.
7. Remove the calibration weight. Then press the
ZERO switch.
The display shows a flashing CAL and the internal weight
recalibration begins. The procedure will take about 30 to 90 seconds.
When the procedure is complete, the display will blank and then
return to its normal weighing mode. The balance is now calibrated to
the external weight and the internal weight is calibrated to the external
calibration weight.
RS-232 Command for CAL 1 Using the Internal Weight
To initiate a CAL 1 using the motor driven internal calibration weight via a RS-232 command, issue the command ACAL[CR].
The automatic internal weight calibration will begin immediately without further user interaction. For a more complete
discussion about RS-232, please see the Bi-directional RS-232 Command Set section.
