CALIBRATE
Menu
Item
This menu item performs a calibration according to what was entered in the
CALIBRA-
TION 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 comple-
tion, 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
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 comple-
tion, 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 pre-
viously 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 pre-
viously 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 pre-
viously 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
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 60), and the
CALIBRATION DATA
must be entered (see “
CALI-
BRATION DATA
Sub-Menu” on page 62).
NOTICE
For maximum accuracy, allow at least twenty minutes of warm-up with the exci-
tation voltage applied to the transducer before calibration.
