HH0308C Auto-Ranging DC/True RMS AC Digital Multimeter 
 
1, DESCRIPTION 
    Thanks for choosing our product as your reliable tool. 
    The HH0308C auto-ranging digital multimeter is designed for measuring resistance, capacitance,        

DC/True RMS AC voltage, DC/True RMS AC current, frequency, duty cycle and temperature, 
testing diodes, transistors and checking continuity. 

This meter is designed for indoor use at altitude up to 2000m, temperature between 5  and 

    40 , the maximum humidity 80% for temperature up to 31º C decreasing linearly to 50% relative  

humidity at 40º C and pollution degree 2. 

    The LCD display is clear and easy to read. The functions of auto-range, auto power shut-off,  
    over-range protection and low battery indication provide you the maximum convenience.     
 
2, SAFETY INSTRUCTIONS 
 

This meter has been designed for safe use, complying with IEC61010.1 CAT II 1000V DC, but 
must be operated with caution. The rules listed below should be carefully followed for safe use. 

2.1 NEVER operate this device when the back cover is open or not properly attached in its place. 
2.2 Make sure that the insulation of leads is not damaged. 
2.3 When BAT appears on the display, change both batteries to maintain accurate  measurement. 
2.4 NEVER apply voltage to the meter that exceeds the specified maximum: DC1000V or AC750V. 
2.5 USE extreme caution when working with voltage over the 36V safe point. 
2.6 NEVER change the position of the function switch during measuring. 
2.7 CHOOSE the correct positions of all function switches before testing. 
2.8 NEVER change any connection on the circuit board of the meter. 
2.9 USE only damp cloth or mild detergent to clean the outside of the meter.
