Measurements of Phase can be expressed in one of
three formats:
Commonly used in circuit analysis
Commonly used in power applications
Audible sound when keys are pressed
Periodically re-zero’s input to prevent drift, useful for
long periods of DC analysis
Unit will only zero inputs if “Zero” is pressed by user
Program 1-6 may be recalled with a direct press of
the function keys (POWER, INTEG etc)
Function will be disabled
The data displayed in zoom 2 may be displayed to
one digit greater resolution than normal, this is
particularly useful when measuring phase at power
line frequencies
Function will be disabled
This allows the user to set different scale factors and
select independently internal / external shunts
separately on each phase
Function will be disabled
Low value blanking will zero to display values under
the following conditions
Input Signal Peak
< 45% of RNG 1
< 25% of RNG 2
< 15% of all other ranges
Function will be disabled
