pressing the left button as often as necessary.
An APPLICATION for the use of the Min Peak Mode: Lets say
you have a circuit that is suspect of losing a connection and
the voltage drops, causing something to turn off or malfunc-
tion. Probing the circuit and monitoring it in Min Peak Mode
will instantly indicate as the circuit drops in voltage. You can
monitor the circuit while wiggling wires and pulling on connec-
tors to see if the voltage drops. Since the minimum voltage
reading is captured and held on the display, you can inspect
it at a later time. You could also perform a battery load test by
monitoring the vehicle's lowest battery voltage while cranking
the starter.
Mode #5 AC Threshold Level Setting for the Peak to Peak De-
tection in Voltmeter Mode" (Mode #1) This mode is only used
to adjust the threshold voltage in "Voltmeter Mode" for Peak
to Peak Detection and Signal Monitoring. To set the thresh-
old level for the peak to peak detection in "Voltmeter Mode",
press right menu button to bring up the menu selections, then
use the left button to highlight "AC THRESHOLD", then press
the right button again to display the AC Threshold voltage
setting. The peak to peak threshold voltage settings loop in-
crementally from 50.0 to 0.2, to 0.5, to 1.0, to 2.0, to 5.0, to 10.0,
and return back to 50.0 again. An audio installer would find the
0.2v setting convenient. Once you select the desired thresh-
old voltage, press and hold the right menu button again to
return to Voltmeter Mode (Mode #1). This AC Threshold setting
determines the amount of AC voltage required to automatically
switch to Peak to Peak Mode and activate the speaker to allow
audible monitoring of the AC signal
