2.1.2. SPAN Calibration Setting (C-3) * Set the CAL-10 setting first.
(1) Hold down “Calibration Switch” and “[POWER] key” to enter Calibration mode.
(2) Then, the scale displays “CAL 1” message after “ONE” message.
(3) Press [ZERO] key two times to display “CAL-3”.
(4) Press [TARE] key and then it displays “zero ” message.
(5) Press [TARE] key and then it displays “midup” message
(6) Load middle weight (ex:1/3 of full capacity) on the platform
(7) Press [TARE] key and then it displays “FULL ” message
(8) Load full weight on the platform
(9) Press [TARE] key and then it displays “middn” message
(10) Load middle weight (ex:1/3 of full capacity) on the platform
(11) Press [TARE] key and then it display “CAL 3” message
* ER
PLUS
uses 3 points calibration to weigh precisely. However, if you want to use 1 point
calibration, set mid-value as “0” in “CAL-10” setting.
2.1.3. Gravity Constant Value Setting (C-9)
Current gravitational Acceleration value is set to 9.7946 m/s
2
.
(1) Hold down “Calibration Switch” and “[POWER] key” to enter Calibration mode.
(2) Then, the scale “CAL 1” message after “ONE” message.
(3) Press [ZERO] to display “C-9”.
(4) Press [TARE] key, and then “ G-1“ message and “9.7946” will be shown. G-1 means
Gravity constant value at the location that the span of scale has been calibrated.
(5) Input a gravitational acceleration value by keypad and press [TARE] key to set.
(6) And then “G-2“ message and “9.7946” will be shown. G-2 means Gravity constant value in
the location that the scale will be used. In this case, G-2 value is not modified yet.
(7) Input a gravitational acceleration value by keypad.
(8) Press [TARE] key to save the gravitational acceleration value, and then “C-9 ” message will
be shown. It indicates
(9) In addition, ER Plus will set G-1 value to G-2 value automatically when you recalibrate at the
new place. Therefore, just set the G-1 value before calibrating the scale.
2.1.4. Calibration factor Setting (C-10) * Refer to CAL-10 Table.
(1) Hold down “Calibration Switch” and “[POWER] key” to enter Calibration mode.
(2) Then, the scale displays “CAL 1” message after “ONE” message.
(3) Press [ZERO] to display “C-10”.
(4) Press [TARE] key, and then “UNIT “ message and “0” will be shown. The first digit,”0” It
means calibration unit is “kg” (0 : kg, 1 : lb)
(5) Input a calibration unit by using keypad.
