• When the logged data item number exceeded 9999 (where
available), the bar-graph will also be used to indicate the
most significant digit of the item number in the order of
10000. That is 1 = 10000, 2 = 20000, ... etc.
• When the memory is full, the data logging mode will be
stopped automatically, and the instrument will then enter the
Auto Power Off mode.
• To guarantee the accuracy of every logged data, the
instrument will stop the data logging mode when the battery
is low, and goes back to the normal measuring mode.
• The data will be stored to the non-volatile memory shortly
after every measurement to maximize data safety. However,
the end-of-data sign can only be stored after the data logging
is finished. Therefore, always "StoP" the data logging
function before switching off the instrument. After the data
logging is finished, you can switch off the instrument for
transportation, storage, or even changing battery.

Analog Bargraph
The analog bargraph provides a visual indication of
measurement like a traditional analog meter needle.
AC Sensing
[AC coupling True RMS]
When measurement is taken by true r.m.s., the measurement
value of input signal becomes the scales of the signal power
and therefore provide more effective values than those
obtained by average value detection. This multimeter implies
this true RMS circuit, which enables measurement of sine wave
and non-sinusoidal waves like square wave and triangular
wave in r.m.s.
