view the offset in mV at the time
of last calibration . The secondary
display will show “OFF” to indicate
“offset” .
• Press the
or
key again to view
the slope in mV/pH at the time of
last calibration . The secondary
display will show “SLO” to indicate
“slope” .
• Press the
or
key again to view

time of last calibration . The sec-
ondary display will show “BUF1”

Note
When the “Measurement input selection” item is set to
