11.3 Calibration Procedure

If you are not familiar with operating the instrument in the SETUP
menu mode, see "SETUP Menu mode" on page 7. A listing of all
menu items is given in "Setup Menu Reference" on page 77.
• Step 1: Wire the transducer to the channel's connector.
See "Wiring" on page 39 for details.
• Step 2: Enter the CALIBRATION TYPE.
You must have the capability to apply either two, three, or
five known displacements to the transducer. The CALIBRA-
TION TYPE menu item allows you to specify how many
known displacements will be applied during calibration.
• Step 3: Enter the CALIBRATION DATA.
Consult the Certificate of Calibration for the transducer when
entering information in the CALIBRATION DATA sub-menu.
• Step 4: Determine the LVDT's electrical null point, then physi-
cally mount it.
The electrical null is the armature position that produces the
least electrical output. Once this point has been determined,
the transducer is physically clamped into position. See
"Electrical Null and Transducer Mounting" on page 45.
• Step 5: Perform the calibration.
Using the CALIBRATE menu item starts the calibration pro-
cess. You will be prompted to apply displacements to the
transducer as required.
