the negative side and the red lead to the positive side of the circuit so
that the test leads are in series with the load to be measured.
➔
Apply power to the circuit.
➔
Read the displayed current.
➔
If ʻOLʼ appears on the display, it indicates over-range. Immediately remove
test leads from the measuring circuit to avoid any damage to the meter.
5. RESISTANCE MEASUREMENT
WARNING:
NEVER CONNECT THE TEST LEAD TO ANY VOLTAGE WHEN THE FUNC-
TION SWITCH IS SET TO . REMOVE ALL POWER FROM THE CIRCUIT BEING TESTED
WHEN CHECKING RESISTANCE. DISCHARGE ANY CHARGED CAPACITORS. NEVER APPLY
THE TEST LEAD TO THE MEASURING CIRCUIT WHEN CHANGING THE POSITION OF THE
FUNCTION SWITCH.
NOTE: The meter will be Auto ranging for this function. If you wish to measure with
Manual range, follow instructions described in Section 9. For manual ranging, start at
the highest range and work down.
➔
Set the function switch to .

ʻ
M
ʼ appears on the display and the LED next
to V/ / / jack turns on.
➔
Plug the red test lead in V/ / / jack
and black test lead in
jack.
➔
Apply the test leads to the resistor
being measured. If the resistor is
part of a circuit, it is necessary to
disconnect one end of the resistor
to avoid any unwanted interference
from the rest of the circuit.
➔
Read the displayed resistance
indicated with proper decimal point
and one of the symbols , K or
M .
