Calibration

The SevenGo pro™ SG8 pH/ORP/ION Meter allows you to perform calibrations with up to five points.

4.4.1 pH settings

If you select your calibration buffer group from one of the six predefined buffer groups in the meter, the buffers
are automatically recognized and displayed during calibration (auto buffer recognition).
The six predefined buffer groups are:
1 MT US
2 MT Europe
3 Merck
4 JIS Z 8802
5 DIN 19266
6 DIN 19267
Tables (B1...B6) for automatic temperature compensation are programmed in the meter for each buffer (see
also Appendix).
You can also follow the buffer setting procedure described below to define your own buffer group , but in this
case auto buffer recognition does not work during calibration.
