Pressing the  key, the meter will cycle through the following
steps in reverse order, i.e. beginning from last buffer.
Note At any time pressing LCD or CAL DATA key the meter will
return to the regular operating display.
• Press the  or  key to view the
time of last calibration. The second-
ary display will show “HOU” to
indicate “hour and minute” while the
primary LCD will show the time as
HH:mm format.
• Press the  or  key again to 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 dis-
play will show “SLO” to indicate
“slope”.
• Press the  or  key again to view
the first memorized buffer at the time
of last calibration. The secondary
display will show “BUF1” to indicate
“first buffer”.
• Press the  or  key again to view
the second memorized buffer (if
present) at the time of last calibra-
tion. The secondary display will show
“BUF2” to indicate “second buffer”.
• Press the  or  key again to re-
turn to the first CAL DATA display
(date) at the time of last calibration.
Note When the “Measurement input selection” item is set to “Digi-
tal Transmitter” the displayed last calibration data refer to the
Digital Transmitter and is stored in that device. This does not
mean that the calibration data of the process controller are
lost, but they come back when changing back the “Mea-
surement input selection” later.
