The Fluke 87 True RMS Multimeter (also referred to as
"the meter") is a handheld, 4000-count instrument that is
designed for use in the field, laboratory, and at home. The
meter combines the precision of a digital meter with the
speed and versatility of a high resolution analog display.
Frequencies between 0.5 Hz and 200 kHz can be
measured with up to 0.01 Hz resolution. The meter is
powered by a 9V battery and has a rugged case sealed
against dirt, dust, and moisture. A snap-on holster, with
Note
Warning
flexible stand (Flex-Stand ), protects the meter from
rough handling. The flexible stand allows the meter to be
stood or hung.
The meter also provides:
A MIN MAX Recording mode, in which the meter
"remembers" the lowest and highest readings,
calculates the true average of all readings taken over
a period as long as thirty-six hours, and displays
these values. The beeper emits a Min Max Alert
when a new minimum or maximum reading is
recorded.
A Peak MIN MAX mode that captures changes as
short as 1 millisecond.
An alternate Frequency Counter mode that measures
duty cycle and displays it as a value between 0.1 and
99.9%.
An Input Alert that causes the beeper to sound if the
test leads are plugged into the wrong input terminals
for the function being performed.
A REL mode that allows you to store a reading in
memory, and display the difference between the
stored value and subsequent readings.
