3.4.4 Measurement Parameters

Press the DISPLAY button to see the following:
Timed Run: Set the measurement duration
(in minutes:seconds) for measurements with
programmed duration.
- The adjustment range is from 00:01 to 99:59,
in 1-second steps.
DAR: Set the time at which the measurements must
be recorded to calculate the DAR (see § 4.6).
This can be used in special applications.
- The first time can be set from 10 to 90 seconds in
5-second steps.
- The second time can be set from 15 to 180 seconds
in 5-second steps.
PI: Set the time at which the measurements must be
recorded to calculate the PI (see § 4.6). This can be
used in special applications.
- The first time can be set from 0.5 to 30 minutes in
0.5- then 1-minute steps.
- The second time can be set from 0.5 to 90 minutes
in 0.5-, 1-, and 5-minute steps.
Press the DISPLAY button to see the following:
Test Type: Choose the type of test: Burning,
Early-Break, or Break at I-Limit.
Maximum Output Current: Set the maximum
output current, from 0.2 to 5mA.
Maximum Output Voltage: Set the maximum
output voltage. This can be useful to prevent
handling errors, thus making it possible to
entrust the instrument to less experienced
users for particular applications (e.g. telephone,
aviation, etc.) where it is important not to
exceed a maximum test voltage.
Example: If the maximum voltage is set to
750V, the measurement will be made at 500V
for the 500V fixed voltage, and at a maximum
of 750V for all other fixed voltages.
The adjustment range is from 40 to 10,000V
(15,000V for Model 6555).
