(11)PEAK Button
The PEAK mode is used to measure the peak
value of a signal. It is useable with AC Current
measurements. Press the PEAK button, the
PMAX annunciator turns on
and the display
shows the maximum peak value. When the
PEAK button is pressed again (less than one
second), the PMIN annunciator turns on, PMAX
annunciator turns off and the display shows the
minimum peak value. When the PEAK button is
pressed for the third time (less than one second),
the PMAX and PMIN annunciators are blinking,
and display shows current input value. The meter
returns to normal operation if the PEAK button is
pressed and held for longer than one second.
(12)VAHZ Button
If VAHZ button pressed in ACV or ACA measure-
ment mode, the meter enters frequency counter
mode with automatic range selection. Therefore,
pressing RANGE button in VAHZ mode doesn't
change the frequency range. However, range
changes the sensitivity of frequency detection.
If the input signal has a small amplitude, the
user shall increase the sensitivity.
(13)MAX / MIN Button
Press button to enter the MAX/MIN recording
mode. When the MAX/MIN button is pressed for
the first time, the "MAX" annunciator turns on, and
the display shows the maximum value. When the
MAX/MIN button is pressed again (less than one
second), the "MIN" annunciator turns on, and the
display shows the minimum value. When the
MAX/MIN button is pressed for the third time (less
than one second), the MAX and MIN annunciators
are blinking, and display shows current input
value. The meter returns to normal operation if the
MAX/MIN button is pressed and held for longer
than one second. Pressing the HOLD button in
MAX/MIN mode makes the meter stop updating
the maximum or the minimum value.
