choose, in temperature measure condition choose C°or F°. in the Diode/Beeper
condition choose Diode or Beeper, in the Ohm/Cap/ Diode/ Beeper condition
choose Ohm, Diode or Beeper.
4.1.4 Hz/DUTY key
Hz/DUTY is a choose key of frequency / duty ratio, worked as the way of triggering.
Under the pattern of frequency survey, pressing the key can choose the pattern
of frequency or duty ratio. Under the pattern of AC voltage or AC electric current,
pressing the key can choose the survey pattern of voltage/frequency/duty ratio or
electric current.
4.1.5 MAX/MIN value hold key
1)Pressing the MAX/MIN key namely enters the MAX pattern, which always
maintains the maximum value of measurement.; And the second pressing of the
key namely enters the MIN pattern, which always maintains the minimum value of
measurement; Pressing again enters the MAX-MIN pattern ,duplicates above
circulates. After entering the pattern of MAX/MIN will automatically enters the
manual measuring range,The time of pressing the MAX/MIN key more than
2 minutes will lead to the quit of MAX/MIN measuring pattern.
4.2 DC/alternating voltage measure
turn the Range switch to V and this time the measuring appliance is set as the DC
voltage measuring range of automatic shift gears. Insert the black pen into COM jack,
and the red table pen into V/Ω/Hz jack. For example, the measuring of DC voltage is
to merge the table pen at the beginnings and ends of the measured electric circuit,
which can directly read the number on the liquid crystal display monitor. If one wants
to measure the alternating voltage, press SELECT key to the pattern of alternating
voltage, and then merge the table pen with the measured electric circuit to read the
showed number. If manually choose measuring scope is needed, press RANGE key
to choose.
4.3 Measurement of alternating/DC electric current
turn the Range switch to the range of electric current, this time the measuring
appliance is set as the direct current automatic shift gears in advance. Insert the
black table pen into COM jack, and the red table pen into 10A orμA/mA jack. If one
wants to measure DC, one can concatenate the table pen with the measured electric
circuit, which can directly read the number on the liquid crystal display monitor; If one
wants to measure alternating current, press SELECT key to alternating current
measuring range, then concatenate the table pen with the measured electric circuit
to read the showed number. If one needs to choose measuring scope manually,
press RANGE. If one does not know the measured electric current scope before
survey, one should set the range key to the highest measuring range and adjust
downward by the files. When the display monitor only displays OL, that is to say,
the measured electric current has surpassed the measuring range and the switch of
measuring range needs to move the high one grade. μA/mA jack represents that the
maximum input current is 600mA. The overload inputs can burn the internal installation
fuse out and should be replaced immediately. 10A jack, without a fuse, the time of
measuring should be less than 10 seconds to avoid the heating of lines, which would
influence accuracy.
