1、70/73 English Instruction Sheet Page 1 70/73 Series III Multimeter Instruction Sheet W Read First: Safety Information To ensure that the meter is used safely, follow these instructions: Never use the meter if the meter or test leads look damaged. Be sure the test leads and rotary switch are in the c

2、orrect position for the desired measurement. Never measure resistance in a circuit when power is applied. Never touch the probes to a voltage source when the test leads are plugged into the 10 A or 300 mA input jack. To avoid damage or injury, never use the meter on circuits that exceed 4800 volt-am

3、ps. Never apply more than the rated voltage between any input jack and earth ground. Be careful when working with voltages above 60 V dc or 30 V ac rms. Such voltages pose a shock hazard. Keep your fingers behind the finger guards on the test probes when making measurements. Warning To avoid false r
