test when changing the test ranges.
7) To avoid electrical shock or damage to the meter; Do not apply more
then 500V between any terminal and earth ground.
8) To avoid electronic shock, use caution when working above 60VDC or
25VAC rms, such voltage pose a shock hazard.
9) When finished the measurement, switch off the power. Be sure to
remove the battery when it is not used for a long time to avoid leakage
problem.
10) Do not tamper with the circuitry to avoid damage.
11) Do not use or store the instrument in a place of direct sunlight, high
temperature and high humidity.

METHOD OF MEASUREMENT
5.1 DCV & ACV MASUREMENT
1) Set the Function range switch at the required position.
2) Connect black test lead to “COM” terminal and red test lead to the
“V/OHM” input terminal.
3) Connect test leads to measuring point and read the display value the
polarity of the red lead connection will be indicated at the same time as the
voltage.
Note:
a) If the voltage to be tested is unknown beforehand, set the
Function range switch to the highest range and work down.
b) When only the figure “1” is displayed over range is being indicated
and the function range switch has be set to a higher range.
c) Never try to measure the voltage above 1000V! Although the
indication is possible to show, there is danger of damaging the
internal circuitry.
5.2 DCA & ACA MEASUREMENT
1) Connect the black test lead to the “COM” terminal and the red test lead
to “A” terminal for a maximum of 0.5A (model DT5801 maximum 2A)
2) Set the function range switch at the required position.
3) Connect test leads to measuring points and read the display value. The
polarity at the red test lead connection will be indicated at the same time as
the current.
Note:
a) If the current range is unknown beforehand, set the function range
switch to the highest range and work down.
b) When only the figure “1” is displayed, over range is being
