 If ʻACʼ does not show on the display, push the SELECT button until 

it appears.

 Apply the test leads to the circuit to be measured.

 Read the displayed voltage. 

 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. The input voltage should not exceed the measure-

ment capability of this meter. 

3. RESISTANCE MEASUREMENT

 

WARNING:

 NEVER CONNECT THE TEST LEAD TO ANY VOLTAGE WHEN 

THE FUNCTION 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 is auto ranging and will automatically display the resistance 
measurements within the overall range of the meter.

 Set the function switch to 

/ / / .

 If  ,   or ʻFʼ appear on the display, push the Select button until  

, K  or M  appears on the display.

 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 .

NOTE: ‘OL’ appears on the display if the test leads are not connected to 
anything.
