Correcting The Internal Mass Value

The balance can correct the internal mass

value within the range shown below. This
function corrects the internal mass value to
conform to an external weight. The corrected
mass value is maintained in non-volatile
memory even if the AC adapter is removed.
The internal mass value is corrected as follows:

Model

The internal mass

The normal range

BM-20

BM-22

20.00000 g

0.15 mg

BM-252

BM-200

BM-300

BM-500

200.0000 g

1.5 mg

Example

: 200.0000 g is corrected to +0.6 mg (200.0006 g). When using a 100 g external weight by

+0.6 mg for the correction, and the weight changed to 200 g, the correction value is +1.2 mg.

1 Perform one-touch calibration. Weigh an external weight and get the correction value.

2 Press

the

ON:OFF

key to turn off the display.

3 While pressing and holding the

key and the

4 Press

the

key to display the function switches.

Set the function table switch and internal mass correction
switch to "

RANGE

key.......The key to select blinking figure.

RE-ZERO

key....The key to change the value of the blinking figure.

key.........The key to store it and return to weighing mode.

CAL

key............The key to cancel current operation.

5 Press and hold the

RANGE

key to enter the function

table and release the key when

is displayed.

6 Press the

RANGE

key several times until

displayed, then release the key.

7 Press

the

key.

Correct the internal mass value using the following keys.

RE-ZERO

(

)key ....The key to increase the value.

MODE

(

)key ........The key to decrease the value.

key...........The key to store the new value and display

the next menu item of the function table.

CAL

key.............The key to cancel this correction and display

the next menu item of the function table.

8 Press

the

CAL

key to return the weighing mode.

9 Press

the

CAL

key to calibrate the balance using the internal mass.

10 Check that the correction has been performed properly with the

external weight. If the value is incorrect, repeat the correction.
