Measurements
Selecting the check box "Manual input" lets you enter the value for Isec
manually, for example, when Isec was measured with a current clamp rather
than at input IAC.
Automatic Test vs. Manual Test
1. Option "Manual input" clear
Automatic test
– Press the I/O (test start/stop) push-button to start the test.
The test voltage increases in a ramp characteristic from 0V to Vtest within
1 second. Then Vtest is kept and injected for a period of 2.4 seconds, the
measurements are taken. Next, the ramp decreases again within
0.3 seconds.
– The automatic test stops by itself, it can now be assessed.
– To repeat the test, first press B
ACK TO T OP, if applicable, and then C LEAR
R
ESULTS.
Manual test
Clearing "Auto" lets you set the test voltage Vtest manually with the handwheel.
– Press the I/O (test start/stop) push-button to start the test. The focus is set
onto the "V test:" entry field.
– Set the value of your choice either by turning the handwheel and/or by
entering it with the numerical keys.
– Now the measurements are taken and displayed.
Vsec: actual voltage at the burden, measured at input V1AC
Isec: actual current through burden, measured via input IAC
Burden: burden in VA: Vsec nom × (Isec act × Vsec nom/Vsec act)
cos
ϕ cosinus of phase angle ϕ
Note: A value set with the numerical keys needs to be fully entered and
acknowledged by pressing either E
NTER or the handwheel before
it is applied to the output. If needed, it can then be adjusted using
the handwheel.
Values set by turning the handwheel are applied instantaneously.
