CPC 100 V1.41

Quick starts in "measuring" state with de-activated outputs, displaying the
measured values in the measurement table of the Quick test card.
The measurements as well as the indication of the binary input’s signal status
(refer to ”Bin.In:” on page 12 of this chapter) are updated with an interval of
approx. 0.5s.
After having set all necessary parameters (more about this in the following
sections), press the I/O (test start/stop) push-button. The Quick test card enters
the "on" state, the set power output value is switched to the
CPC 100 outputs,
the measuring continues.

saves the currently
measured values and "freezes" their display in the measurement table. Both the
"measuring" and the "on" state remain active, the measurement continues in a
new line of the measurement table.
While in "on" state, pressing the I/O (test start/stop) push-button terminates the
test. The
CPC 100 outputs are turned off, and Quick returns to the "measuring"
mode.
Pressing the S

menu key opens the Settings page. The Settings
page allows setting the test cards individually. As a rule, do not use the Settings
page but the Device Setup tab in the Options view (see ”Device Setup” on
page 2-33) to set the test cards. For more information, see ”Settings Page” on
page 2-28.
Note 1: When testing capacitive test objects using voltages
≥
500V, make
sure that the test object’s capacity does not exceed 25nF.
Together with the test object’s capacity, the leakage inductance of
CPC 100 internal output transformer forms a series resonant circuit.
Especially at frequencies
>
50/60Hz this may result in voltage
superelevation.
Note 2: Never use Quick to measure the resistance of windings with a high
inductance because turning off the DC source results in life-
threatening voltage levels.
For this kind of measurement only use the special winding resistance
