4.4 Summary of the measuring modes
The instrument was designed for simple programming, so as to cut down the time needed
to prepare measuring.
The instrument is equipped with 25 memory locations (parameters – P) for storing the
various ways of measuring:
Configuration Factory setting Modifiable
P01 - P19 Yes yes
P20 - P25 Yes no
Each configuration can be reached both by the increase and by the diminish key, as these
work in a circular fashion: decreasing from P01 leads to P25, increasing from P25 leads to
P01. This makes it possible to reach the location of interest as soon as possible.
The purpose of the pre-set configurations is to allow performance of measures without
wasting time in setting up.
The purpose of the non-modifiable configurations is that of making the most common
insulation measurement types constantly available.
Description of the measuring parameters
• Voltage V2: Final voltage value wanted for test performance.
• Time T2: Duration time for voltage V2.
• Voltage V1: Starting voltage during measuring (only in PROGR mode).
• Time T1: The time for the output voltage to rise from the voltage value V1 to
the value V2 (only in PROGR mode).
This instrument is designed for use in a simple and intuitive manner, and provides the
following possibilities:
- Direct use of the factory-set configurations for the most frequent cases.
- Direct use of previously set configurations.
- Extemporaneous configurations when the measurement is not included among
those already present.
