Automatic Calibration
Automatic Calibration is selected when you wish the instrument to determine
the individual axis coefficients for the specific transducer you are using; hence a
vibration calibrator is required.
The Multi-purpose type Excieo instrument (GA2005M) allows the calibration of
the following transducers: -
Hand Arm (10mV/g) – HARM mode
Whole Body (100mV/g) or (1000mV/g) – WBV mode
Single Axis (100mV/g) or (10mV/g)– SINGLE mode
Custom (10mV/g) or (100mV/g) or (1000mV/g) – Custom Mode
Where different transducer sensitivities are available it is only possible to store
calibration information for one transducer. You will be asked to re-calibrate if
the Accelerometer sensitivity is changed.
The GA2005H HARM Excieo meter only allows for calibration of a 10mV/g tri-
axial transducer.
The GA2005S Single Axis Excieo meter only allows for the calibration of an
individual axis specifically for single axis transducers. 10mV/g or 100mV/g
transducer sensitivities can be selected however it is only possible to store
calibration information for either 10mV/g or 100mV/g and not both. You will
be asked to re-calibrate if the Accelerometer sensitivity is changed.
It is recommended that automatic calibration is performed using the Castle
Vibration Calibrator GA606 in conjunction with its supplied Petro wax mounting
compound for transducers other than KD1009.
