5-2 ACTUAL LOAD CALIBRATION (CAL SET)
The zero point and span are calibrated using a calibration weight. When making calibration for the first time, it is
necessary to set the unit, decimal point position, minimum division, and capacity in advance, using the calibration-related
functions mentioned in 5-3.
In order to avoid influence by temperature drift; carry out this calibration 10 minutes or more after turning on the power.
Step 1
Remove the cover from the calibration switch located at the lower left of the front panel and press the
[CAL] key (found inside). “CAL” is displayed to inform you that the indicator is entering the calibration
mode.
•
Note: When calibration is not required, press the [ESC] key. The indicator will return to the normal mode.
Step 2
Press the [ENTER] key. The indicator has entered the calibration mode and “CAL SEt” is displayed.
The right most digit starts blinking.
ZERO CALIBRATION
Step 3 Press the [ENTER] key. The main display section displays “CAL 0.”
When you want to monitor the current weight value, press the [SETPOINT] key. The Subdisplay section
displays the value. Pressing the [SETPOINT] key again erases this display.
When zero calibration is not necessary, press the [F] key. The indicator will go to span calibration
(Step 5).
Step 4
With no weight placed on the system, press the [ENTER] key after the motion-detect mark is turned off.
The Subdisplay section displays “——” for about 2 seconds.
•
When “C ErrXX” is displayed, there is an error taking place. See 5-4.
SPAN CALIBRATION
Step 5 The main display section displays “CAL SPn,” the Subdisplay section displays the weight value (current
weighing capacity, set value for CALF-04), and the lowest digit of the weight value blinks. Adjust to the
calibration weight value that you have on hand, using the [<], [>], [
∧
] , and [
∨
] keys.
When you want to monitor the current weight value, press the [SETPOINT] key. The Subdisplay section
displays the value. Pressing [SETPOINT] again replaces this display with the weight value.
When span calibration is not necessary, press the [ESC] key twice. You are returned to the normal mode.
Step 6
Place the calibration weight on the system and press the [ENTER] key after the motion-detect mark is
turned off.. The Subdisplay section displays “——” for about 2 seconds.
•
When “C ErrXX” is displayed, there is an error taking place. See 5-4.
Step 7
The main display section displays “CAL End.”
When you want to readjust the span, press the [F] key. This will allow you to continue span calibration.
Step 8 Press the [ESC] key. The main display section displays “CAL SEt” and the actual load calibration data is
saved in the EEPROM.
Step 9
This state is the same as in Step 3. Press the [ESC] key once again. The indicator will return to the
normal mode and the weight value is displayed.
