6 System options
Press SYS to access the system options.
The unit’s real-time clock can be set to the current date
and time.
The display brightness may be set to “low” or “high”
depending on viewing conditions.
Measurements of phase can be expressed in one of three
conventional formats:
-180 to +180 (commonly used in circuit analysis)
0 to -360 (commonly used in power applications)
0 to +360
The measurement is exactly the same, it is only the way
that it is expressed that changes.
Each key press is normally accompanied by an audible
‘beep’ as well as the tactile ‘click’. The ‘beep’ can be
disabled for quiet environments if the feel of the key is
sufficient feedback
Regular autozero measurements can be suppressed.
The 4 main function keys, POWER, HARM, RMS, SCOPE,
can be used to load stored configurations as a “one-touch”
way of configuring the instrument for specific applications.
This is particularly useful in a production environment
where an operator has a small number of specific tests to
perform.
Independent ranging control for multi-phase instruments
can be switched on or off.
