indicated and the function range switch has be set to a higher
range.
c) Excessive current will below the fuse that must be replaced when
the input is from “A” terminal. Fuse type is 0.5A (model DT5801A
use 2A).
d) A fuse does not protect the 20A range; maximum 10A continuous
or maximum 20A measuring time must be less than 15 seconds.
5.3 RESISTANCE MEASUREMENT
1) Connect black test lead to “COM” terminal and red test lead to the
“V/OHM” input terminal.
2) Set the function range switch to the OHM range.
3) Connect the test leads across the resistance under measurement and
read the display value.
Note:
a) The polarity of the red test lead is “+”.
b) When the input is not connected, i.e. at open circuit the figure “1”
will be displayed for the over range condition.
c) If the resistance value being measured exceeds the maximum
value of the range selected an over range indication “1” will be
displayed and function range switch must be set to a higher
range.
d) 200MΩrange has a 10 digits (1MΩ) constant, the figure will
appear in short circuit status it should be subtracted from
measurement result, for instance: when measuring 100MΩ
resistor, figure 101.0 will shown in display and the last 10 digits
should be subtracted.
5.4 CAPACITANCE MEASUREMENT
1) Set the function range switch at the “Cx” position. Before connecting the
capacitor, the display that could be zeroed automatically slows.
2) Connect the test capacitor to the “Cx” input socket (not test leads) and
read the display value.
Note: The tested capacitor should be discharged before the testing
procedure. Never apply voltage to the “Cx” input socket, or serious damage
may result.
5.5 FREQUENCY MEASUREMENT
1) Set the function range switch at the required “Hz” position.
2) Connect test leads to measuring points and read the display value.
Note: Do not apply more than 250V rms to the input. Indication is possible a
