CALIBRATE
Menu
Item
This menu item performs a calibration according to what was entered in the
CALI-
BRATION TYPE
and
CALIBRATION DATA
menu items.
If the
CALIBRATION TYPE
is Shunt Calibration...
• The display will read
DOING SHUNT CAL
, and prompt you to
APPLY 00000 UNIT

S. When you have applied this load to the transducer, press [ENTER].
• The display will then read
WORKING
and calibration will take place. Upon com-
pletion, the display will indicate
DONE
and the instrument will return to the RUN
mode.
If the
CALIBRATION TYPE
is mV/V Calibration...
• The display will read
DOING MV/V CAL
, and prompt you to
APPLY 00000 UNIT
(where
00000 and UNIT are previously entered as

and calibration will take place. Upon com-
pletion, the display will indicate
DONE
and the instrument will return to the RUN
mode.
If the
CALIBRATION TYPE
is 2-Point Known Load Calibration...
• The display will read
DOING 2POINT CAL
, and prompt you to
APPLY 00000 UNIT
(where 00000 and UNIT are previously entered as
KNOWN POINT 1/2
and

, then
APPLY 01000 UNIT
(where 01000 and UNIT are
previously entered as
KNOWN POINT 2/2
and
DISPLAY. UNITS
). When you have
applied this load to the transducer, press [ENTER].
• Upon completion, the display will indicate
DONE
and the instrument will return to

NOTICE
Before performing a calibration, the transducer must be connected to the
instrument, the
CALIBRATION TYPE
must be selected (see “
CALIBRATION TYPE
Menu Item” on page 67), and the
CALIBRATION DATA
must be entered (see “
CALI-
BRATION DATA
Sub-Menu” on page 69).
NOTICE
For maximum accuracy, allow at least twenty minutes of warm-up with the exci-
tation voltage applied to the transducer before calibration.
