5-10. HOLD and AUTO HOLD measurements
The HOLD mode can keep the measured value on the primary
display. Press [HOLD] button, the last reading is held on the display
in all function. To release the HOLD function, just press [HOLD]
again.
The AUTOHOLD mode allows you to keep your eyes fixing on the
probes when taking measurements in difficult or hazardous
circumstances, then read the display when it is convenient and safe.
Press [SHIFT][AUTOHOLD] in sequence into AUTOHOLD mode,
every time when the value is more than the 8% of full scale, and
with 200 counts of different value compared with the previous
AUTOHOLD value, the data on the primary display will be updated.
In the AUTO range mode, when the value is less than 10% full
scale and more than 0.8% full scale, it will change range downward
automatically. If want to release AUTOHOLD function, press
[SHIFT] [AUTOHOLD] in sequence.
5-11. COMPARE MEASUREMENT
In Compare mode, can set the maximum and minimum value to
compare with the current measured value. The secondary display
will show “Hi” when the measured value is more than the
maximum value, will show “Lo” when the measured value is less
than minimum value, and will show “Pass” in other status. The
functions of DCV(DCmV), ACV(ACmV, AC+DC), DCA(DC20A),
ACA(AC20A), OHM, and Capacitance have their own maximum
and minimum value setting separately according to the procedure as
follows:

value with the ranges of 5V, 50V, and 500V, the secondary display
will show AC component of signal with the range of 500mVac,
100kHz frequency response. The function is easy to detect DC and
AC components of signal simultaneously.
If want to leave the RIPPLE mode, just switch to other main
