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
(where
00000 and UNIT are previously entered as
ZERO SCALE VALUE
and
DISPLAY. UNITS
.
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 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
DISPLAY.
UNITS
). When you have applied this load to the transducer, press [ENTER].
• The display will read
WORKING
, 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
the RUN mode.
If the
CALIBRATION TYPE
is 3-Point Known Load Calibration...
• The display will read
DOING 3POINT CAL
, and prompt you to
APPLY 00000 UNIT
(where 00000 and UNIT are previously entered as
KNOWN POINT 1/3
and
DISPLAY.
UNITS
). When you have applied this load to the transducer, press [ENTER].
• The display will read
WORKING
, then
APPLY 00500 UNIT
(where 00500 and UNIT are
previously entered as
KNOWN POINT 2/3
and
DISPLAY. UNITS
). When you have
applied this load to the transducer, press [ENTER].
• The display will read
WORKING
, then
APPLY 01000 UNIT
(where 01000 and UNIT are
previously entered as
KNOWN POINT 3/3
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
the RUN mode.
NOTICE
Before performing a calibration,
•
the transducer must be connected to the instrument,
• the channel’s Excitation and Signal Jumpers must be set,
• the
CALIBRATION TYPE
must be selected (see “CALIBRATION TYPE Menu Item”
on page 113), and
• the
CALIBRATION DATA
must be entered (see “CALIBRATION DATA Sub-Menu”
on page 115).
NOTICE
For maximum accuracy, allow at least twenty minutes of warm-up with the exci-
tation voltage applied to the transducer before calibration.
