Page 2: Warranty
If the defect has been caused by a misuse or abnormal operation conditions, the repair will be billed at a nominal cost. SAFETY INFORMATION DT830 series multimeter have been designed according to IEC-1010 concerning electronic measuring instruments with a measurement category (CAT 600V), the max. - Page 3 MAINS-derived circuits. In the latter case, the transient stresses are variable; for that reason, its necessary that the transient-withstand -capability of equipment is made known to the user.). Don’t use the equipment for measurement within Measurement Categories II,III and IV. http://www.histest.com http://www.all-sun.com...

Page 4: Maintenance
CAUTION To avoid possible damage to the meter or to the equipment under test, follow these guidelines: Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance. Use the proper terminals, function, and range for your measurements. Before measuring current, check the meter's fuses and turn power off to the circuit before connecting the meter to the circuit. -
