pH Buffer
This is a multiple variable function that allows the user to choose which
pH buffer sets that will be utilized in the 2-point calibration mode. The
Q46H contains 3 sets of buffer tables with compensation values ranging
from 0 to 95 °C. During 2-point calibration, the instrument will
automatically identify which buffer is being used and compensate for the
value based on the built-in tables. The order in which the buffers are
used during calibration is unimportant, since the system automatically
chooses the correct buffer.
The default setting for this feature is OFF, which disables the auto-
recognition function. Press ENTER to change this setting. The buffer
table set options are: 1: [4/7/10], 2: [4/7/9.18], and 3: [4.65/6.79/9.23].
See Figure 24 for buffer Tables. Once the buffer set is selected, press
ENTER and the message Accepted! will be displayed on the lower line
