Peak Hold Mode (P-H)
The Peak hold function allows the EEDM575D to
display the the maximum and minimum peak volt-
age or current. This is helpful when measuring
inrush current.
NOTE: Peak mode can display up to 70 counts on
the display when first activated. For exam-
ple, if the EEDM575D is set to the ACA func-
tion and manually ranged to the 40A range,
when P-H is activated the display can read
up to 0.70. This is normal for this function.
1.
Manually select the range for the function and
set the meter up to perform a measurement as
outlined earlier in this manual.
2.
Depress and hold the P-H button until CAL is
displayed. Once CAL clears from the display
you may make a measurement. Press P-H
repeatedly to cycle through the maximum and
minimum peak readings. Press and hold the
P-H button for two seconds to return to nor-
mal operation.
For inrush current, after CAL clears press the
P-H button and then supply power to the
device under test. The EEDM575D will capture
the maximum and minimum peak inrush.
