Page 4: Overview
Overview Warning To avoid electric shock or personal injury, read the “Safety Information” and “Rules for Safety Operation” carefully before using the Meter. Pocked-Sized Digital Multimeter (hereafter referred to as “the Meter”) is a 3 3/4 digits with steady operations, fashionable structure, low power consumption and highly reliable hand-held measuring instrument. - Page 5 KMD-S04 This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category (CAT. II 300V) and double insulation. CAT. II: Local level, appliance, PORTABLE EQUIPMENT etc., with smaller transient voltage overvoltages than CAT. III Use the Meter only as specified in this operating manual, otherwise the protection provided by the Meter may be impaired.

Page 6: Rules For Safe Operation
KMD-S04 Rules For Safe Operation Warning To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following rules: Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case (or part of the case) is removed. - Page 7 KMD-S04 explosive, inflammable and strong magnetic field. The performance of the Meter may deteriorate after dampened. When using the test leads, keep your fingers behind the finger guards. Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes or capacitance.
