Refer all servicing to qualified personnel. • When the low battery symbol is displayed on the LCD, replace the battery immediately to ensure measurements are precise. • The function range switch must be placed at the correct measuring location. • Signals detected are not allowed to exceed the limit value so as to prevent electric shock and instrument damage. • Gears of range switch are not permitted to change during measuring, in order to help prevent electric shock and instrument damage. • After each measurement is completed, it is necessary to disconnect the probe from the circuit under test. • Therefore, once measurement is complete, turn off the power supply and disconnect the probe and circuit under test. • When measuring voltage higher than DC 30V or AC 30Vrms, be careful when using the instrument in order to avoid electric shock. • Do not use the instrument at high temperatures or humidity. • Do not store the instrument in a damp or humid environment as moisture is likely to make the Multimeter’s performance deteriorate. • When cleaning, use a damp cloth and a mild detergent to clean the instrument’s outer case. • Do not use any chemicals, abrasives or solvents that could damage the instrument.
