Craftsman 19741 Owner's Manual

SAFETY INSTRUCTIONSThis meter has been designed for safe use, but must be operatedwith caution. The rules listed below must be carefully followed forsafe operation.1. NEVER apply voltage or current to the meter that exceeds thespecified maximum:Input LimitsFunction MaximumInputV DC, VAC, Frequency, Duty Cycle 600V DC/ACAAC, ADC 400A DC / ACResistance , Diode test , Continuity 250V DC/ACCapacitanceTemperature(°F/‘C ) 250V DC/AC2. USE EXTREME CAUTION when working with high voltages3. DO NOT measure voltage if the voltage on the "COM" inputjack exceeds 240V above earth ground4. DONOT measure current of circuits whose voltage is greaterthan 240V above earth ground5. NEVER connect the meter leads across a voltage sourcewhile the function switch is in the resistance or diode mode.Doing so can damage the meter6. ALWAYS turn off the power and disconnect the test leadsbefore opening the doors to replace the fuse or batteries7. NEVER operate the meter unless the back cover is in placeand fastened securelyANSAFETY SYMBOLSThis symbol adjacent to another symbol,terminal or operating device indicates that theoperator must refer to an explanation in theOperating Instructions to avoid personal injuryor damage to the meterThis WARNING symbol indicates a potentiallyhazardous situation, which if not avoided, couldresult in death or serious injuryThis CAUTION symbol indicates a potentiallyhazardous situation, which if not avoided, mayresult in damage to the meterThis symbol advises the user that theterminal(s) so marked must not be connected toa circuit point at which the voltage, with respectto earth ground, exceeds (in this case) 600VAC or VDCThis symbol adjacent to one or more terminalsidentifies them as being associated with rangesthat may, in normal use, be subjected toparticularly hazardous voltages. For maximumsafety, the meter and its test leads should notbe handled when these terminals are energizedThis symbol indicates that a device is protectedthroughout by double insulation or reinforcedinsulation
