9060-Zirconia Analyser
If 'AUTO CAL' is selected, the output channel is calibrated when 'Auto Cal' is initiated from
the keyboard (See Section 6.3).
If 'MAN CAL' is selected, it is necessary to trim both ends of the 4-20mA output range
using the 4mA and 20mA options in this menu item. Selecting 'MAN CAL' inhibits the
'Auto Cal' process of this channel.
Always do the 4mA trim first, and then the 20mA trim. After trimming both ends of the
scale, return the 'CALIBRATION OPTIONS' menu option back to 'MAN CAL' (not 'AUTO
CAL'), or the calibration factors will be over written by the next 'AUTO CAL'.
For more details on calibrating the output channels, see Section 6.3.
NOTE: The transmitter will only stay in either '4mA TRIM' or '20mA TRIM' modes for 30
minutes before it automatically returns to 'MAN CAL'.
