Selection of LOAD / TIME CONSTANTS Z1, Z2, Z3
This is used to select the time constant Z of the current regulator:
Z1 is set for purely resistive devices under test.
The time constants Z2, Z3 are selected for devices under test that have an inductive component.
The instrument does not automatically detect inductive devices under test. For time-critical
applications, one can use trial and error to find out whether a faster measurement is possible by
selecting a shorter time constant. Start with the longer time constant Z3 and select the next
shorter time constant Z2. If the same measurement result is obtained, you can then select the
shorter time constant for all further measurements. Always short-circuit the device under test
before disconnecting it.
For Z2 and Z3, the measuring range cannot be changed while the measurement is in progress.
Danger warnings for Z2, Z3
A DANGER warning flashes in the display after pressing START. The DANGER warning is
displayed during the measurement and for one second after pressing the STOP button. Just
because the danger warning is no longer displayed does not mean that there is no longer any risk.
Always short-circuit the device under test before disconnecting it.
Inadmissible instrument settings
The time constants Z2, Z3 cannot be used in conjunction with automatic measuring range and
alternating measurement mode.
