6. If the displayed value during the calibration check was higher than

100.0000g (for example: 100.0005), then the internal calibration

adjustment value needs to be decreased by 0.0005. Press CAL

repeatedly to decrease the weight value in 0.0001g increments until

the new correction value is reached.

7. Press TARE to save the weight value, then press On/Off button to

return to standby mode.

8. Run the Quick-Cal program and check the results with the 100g

calibration weight. If the displayed value is off, repeat the

adjustment steps.

4-3 MANUAL CALIBRATION (Models W3100-120 and W3100-210)

Plug in and pre-warm your balance at least 30 minutes before

performing a the calibration procedure

 Press the Power button to turn on the balance

 "0.0000 g" will be displayed;

 Press CAL key, "CAL100" will be displayed.

 Choose "CAL 100" for a 100g weight or "CAL 200" for a 200g

weight by pressing TARE.

 Press CAL key again and "CAL ..." is displayed .

 Carefully place an external calibration weight of 100g or 200g (it

is recommended to use the calibration weight included with your

balance, or supplied by Benchmark Instruments) on the center of

the pan then close the doors; the balance will calibrate to the

weight and display 100.0000 (or 200.0000) when complete.

Note: After calibration, check that the tolerance between the displayed

value and the calibration weight value is no more than ±0.0002 g.

Otherwise, repeat the calibration steps.

4-4 LINEAR CALIBRATION

If after manual or internal calibration, the displayed weights across

the range of the balance are not accurate, linear calibration is required.

Linear calibration requires calibration weights 50g, 100g, and 150g.

Plug in and pre-warm your balance at least 30 minutes before

performing the linear calibration procedure.
