Performing 2-Point Calibration - OHAUS STARTER 3100 Manual De Instrucciones

STARTER 3100 Bench pH Meter
When STARTER 3100 is in pH measurement mode (see 4.2); place the pH electrode in a
calibration buffer, stir 5 seconds, wait for 30 seconds, then:

Press
and appear on the top of the screen,

The meter reaches endpoint automatically according to the preselected auto-endpoint
mode, the calibration point pH value (e.g. 7.00) with the temperature display on the screen.
The 1-point calibration is finished; There are now 3 options (OHAUS recommends conducting at
least a 2 point calibration);

Performing 2-point calibration


Perform 1-point calibration as described above.

Rinse the pH electrode with pure water and wipe off with tissue.

Place the electrode in the next calibration buffer, stir and wait, then press
displays on the bottom left of the screen and "
and appear,

The meter reaches endpoint according to the endpoint mode, the calibration point pH value
(e.g. 4.01) with the temperature display on the screen.
The 2-point calibration is finished. There are 3 options:
1. Press
2. Press
shown on the display for 3 seconds then return to the measurement screen.
