And ВМ-500 [31/88] Automatic self calibration

BM series 29

8.2. Automatic Self Calibration (For variation of ambient temperature)

Automatic self calibration due to changes in temperature

This function automatically calibrates the balance when the balance detects an ambient

temperature change. If GLP output is selected in the function table, the balance outputs the

calibration report or stores the data in memory. Automatic self calibration functions even if the

display is turned off (standby state). Refer to "9.1. Permit Or Inhibit" for the operation.

Caution

Place nothing on the weighing pan during automatic self calibration.

If something is on the weighing pan, the balance decides that it is in use and does not

perform automatic self calibration.

When weighing a light sample, using a long term weighing or installing the balance in a

system, turn off automatic self calibration.

Note When turning on the balance with nothing on the pan, if a sample heavier than 0.5 g is

placed on the pan, the balance detects the state that a sample is placed on the pan and

does not perform the automatic self calibration.

The mark is " prior notice indicator of automatic self calibration".

When the balance detects a change in ambient temperature, this indicator blinks

and automatic self calibration is required. If the balance is not used for several

minutes with this indicator blinking, the balance performs automatic self calibration.

The environment will affect the time that the indicator blinks.

The balance is measuring calibration data. Do not allow vibration or drafts to affect

the balance while this indicator is displayed. After calibration, the balance returns

to indicate the previous display.

Advise

The balance can be used while the indicator blinks. But, it is recommended that to maintain the

accuracy, stop using the balance and confirm that there is nothing on the pan and allow the

balance to perform self calibration.

8.3. One-Touch Calibration (For Common Use)

This function calibrates the balance using the internal mass.

The only operation required is to press the CAL key.

1 Connect the AC adapter and warm up the balance for at

least one hour with nothing on the weighing pan.

2 Press the CAL key to display Cal in .

3 The balance performs calibration using the internal mass.

Do not allow vibration or drafts to affect the balance.

4 If GLP output is set, glp is displayed, the calibration test report is

output to the RS-232C interface and is stored in memory. Refer to

"GLP output (info)" and "Data memory (data)" of the function table,

"11.2. GLP Report" and "12. Data Memory".

end is displayed after the calibration.

5 The balance will automatically return to the weighing mode after calibration.

6 Confirm weighing accuracy using calibration test (CC in).
