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.
