3-1 Preparation and Caution before Measurement 

 

1. Allow at least 30 seconds after switching on before taking measurements. 
2. Remove test leads from the circuit under test, before changing the measurement range. 
3. If the meter is used near equipment that generates electro-magnetic interference, the display may be unstable  
    or indicate incorrect measurement values. 

4. 

Maximum rated voltage to earth for voltage and current measurements terminals is 600V AC/DC CAT II,  

    300V AC/DC CAT III. 
 

3-2 Voltage Measurements 

 
1. Set the rotary switch to the required position. 
2. Set the DC/AC switch to the required position. 
3. Connect black test lead to "COM" terminal and red test lead to the "V

Ω

Hz" input terminal. 

4. Connect test leads to measuring points and read the displayed value. 
5. "Warning :  Do not exceed 600V d.c. or 600V a.c. limits stated in the specification".
