PART 1 – INTRODUCTION
The Kaman digiVIT is a revolutionary inductive displacement measuring instrument. The
digiVIT simplifies use of a variety of Eddy Current sensors for precision measurements of;
displacement, position, vibration, run-out, etc, in typical and difficult applications. The digiVIT is
user configurable and adjustable.
The digiVIT does not require any special factory setup to work with most inductive sensors. It
incorporates a self tuning mechanism that optimizes set up for a given sensor, cable length,
conductive target material, and range. Using the front panel controls, the digiVIT can easily be
calibrated, temperature compensated, and adjusted for a variety of voltage and current output
options.
Getting Started
1.1 Connect Power
A +24 VDC power supply capable of supplying 0.13A is required to power digiVIT. Connect the
power supply to the digiVIT terminal block pins 1 and 2 (reference Part 2 on connections).
1.2 Connect the Sensor
The sensor is connected to the SMA connector. On application of power, if no sensor is
connected or the digiVIT senses and open connection the message 'No Sensor' will appear on
the display. If, the sensor is defective or its resistance is too low, the message 'Bad Sensor' will
be displayed. If the unit was previously calibrated, the display may indicate a voltage, current
or percentage depending on how the display was configured. If voltage or current was not
selected, the default display is percent of full scale.
1.3 Calibrate the Sensor
If factory calibration has not been performed, the sensor must be calibrated before it will
function properly. Reference PART 6 on calibration examples.
1.4 Connect the Outputs
Connect either the analog voltage output, current output, or use the Ethernet port over a UDP
interface. For the analog voltage and current output, output ranges (i.e. 0-5V, +/-5V, 0-10V, +/-
10V, 0-20mA, or 4-20mA) can be selected using the front panel menu.
