12.2 Voltage measurement
(Motion channel)
Confirm that you want to continue with the calibra-
tion of the voltage scale.
Adjust Voltage
<Yes> No
Note This action changes the scale factor and must
be done by qualified personnel only.
EGIL as a Volt meter
1]
Connect a stabilized voltage source with a
calibrated volt meter in parallel to the mo-
tion input, pin 1 and 3.
2]
Adjust the voltage in the motion circuit to
about 4 V. Note: If too low or too high volt-
age is applied, the display will indicate “out
of range!”.
Test Voltag

3]
Press ENTER to continue.
Loading the precise voltage value
4]
Enter the correct value of the voltage used
during the calibration procedure red out
from the volt meter.
Source Voltage
xxV
5]
Press ENTER to finish the calibration process.
Note
During the calibration most of the keys and
knobs are disabled.
12.3 EGIL as a timer
1]
Connect the start input of a calibrated fre-
quency counter to the close coil input/output
of EGIL.
2]
Connect the stop input of the frequency
counter to the open coil input/output of
EGIL.
3]
Set the delay time of open to 500 ms.
4]
Select a C-O operation.
5]
Connect timing channels L1/L2/L3 to the open
input/output.
6]
Turn the MEASURE knob.
7]
Compare the timing result of EGIL with the
result of the frequency counter.
Note
This is a verification of the timing accuracy.
There are no possibilities of adjustments.
