Additional Features

Input Test Lead Warning

The meter emits a continuous tone when a test lead is placed in the mA or A input
jack and the Function/Range Switch is not set to a correct current position. (If the
meter is connected to a voltage source with leads connected for current, very high
current could result). All current ranges are protected by fast acting fuses.

MIN MAX Measurements (Model 5XP-A only)

The MIN MAX feature reads and updates the display to show the maximum or
minimum value measured after you press the MIN MAX button.
Pressing the MIN MAX button for less than 1 second will put the meter into a mode
of displaying the maximum or minimum readings. Each time the button is pressed,
the meter will cycle to the next display mode. Press the MIN MAX button for more
than 1 second to disable this feature.

Auto Power Off (Models 15XP-A and 35XP-A only)

Auto Power Off is a battery saving feature that puts the meter into a sleep mode if
the Function/Range Switch has not changed position in the last 10 minutes. To
wake the meter turn the Function/Range Switch to another position.
The Auto Power Off feature can be disabled to keep the meter from going to sleep.
To disable the Auto Power Off feature use the following procedure:
1. Set the Function Switch to OFF.
2. Press and hold the Range button while turning the Function Switch from OFF
to the desired function.
3. Release the Range button. The Auto Power Off feature will remain disabled until
the meter is turned off and then on.

HOLD Measurements

The HOLD button causes the meter to capture and continuously display a
measurement reading. To use the HOLD feature make a measurement, and then,
after the reading has stabilized, momentarily press the HOLD button. You can
remove the test leads and the reading will remain on the display. Pressing the
HOLD button again releases the display.
