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 correct 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-amps. 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 readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator (N) appears.
