DME1500
MEASUREMENT TUTORIAL E-21
2.3.2 AC+Hz measurements
The function can be selected only when ac range is selected. Press
[SHIFT] key, then press [AC+Hz] key, the secondary display
shows the frequency of the input signal that is higher than the sen-
sitivity. The frequency measurement does not depend on the max/
min, rel, or hold mode. In this mode, the reading rate of the DMM
may be slower than the normal state.
To release the AC+Hz function, press [SHIFT] key, then press
[AC+Hz] key again. The dBm mode and AC+Hz mode are not
selected concurrently.
2.3.3 AC+DC measurements
The function can be selected only when voltage or current func-
tion is selected. Press [AC+DC] key, the primary display shows
the true rms value of the input signal including the ac component
and dc component. In this mode, the reading rate of the DMM is
slower than the normal state.
To release the AC+DC function, press other function (voltage ac
or dc, current ac or dc, R, C, Continuity Beeper, Diode Test) key.
2.3.4 MAX/MIN measurements
The MAX/MIN mode causes the DMM to hold the lowest and
highest readings. Press [MAX/MIN] key to the MAX mode. The
highest will be displayed in continuous input. In the MAX mode,
press [MAX/MIN] key to the MIN mode. The lowest will be dis-
played in continuous input. In the MIN mode, press [MAX/MIN]
key to release the MAX/MIN mode.
2.3.5 REL measurements
When the [REL] key is pressed, the DMM stores the present read-
ing and displays subsequent measurements as the difference
between the measured value and the stored reading.
In the MAX/MIN mode, set [REL] key to the REL mode. The
maximum or minimum reading will become the relative base.
