TAKING MEASUREMENTS
The Sensor Cable supplied with EDI-53UTM consists of 6-core cable with 7-pin circular connectors on
one end & 6-pin circular connector on other end of the cable. Fig. 1 shows how the EAN-70M tilt
sensor is connected to the EDI-53UTM indicator using the supplied sensor cable.

PREPARING SETUP DATA
To measure the tilt meter output with EDI-53UTM at least one channel has to be setup using
calibration coefficients as described below. This channel can then be used to measure the output from
any EAN-70M Portable tilt meter.
1.
Ch No.
Enter the channel number (i.e. transducer number) that you want to
assign to the portable tilt meter for taking readings. As the same
portable tilt meter will be used for taking measurements from different
tilt plates, only a single channel need to be configured.
2.
Units
Press Key ‘9’ when prompted for ‘Units’, to select ‘blank’.
3.
Initial Reading
Press Key ‘0’ when prompted for ‘IR’
4.
Gauge Factor
2 / [Tilt Meter gauge factor in Volts/Sin(90
°
)]
(For EAN-70M
±
15
°
range tilt meter, enter 0.125 )
5.
Coefficient A
This value should be left at zero
6.
Decimal Point ‘DP’
Press key ‘4’ when prompted for DP, to see the sine value up to four
significant decimal places.
NOTE:
The EAN-70M 15
°
tilt meter outputs 4.1411 V (nominal) at 15-degree tilt, which corresponds to a sine
value of 0.2588. However, to increase display resolution the EDI-53UTM attenuator setting is kept at
2:1 which allows to display sine value of up to 0.2500 corresponding to a tilt angle of 14.48 degrees
instead of 15 degrees. As the EAN-70M is generally used to measure small angles, typically less than
±
5 degrees, this should not be a disadvantage.
