• Be sure the test leads and 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. • 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. WWarning To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator (M) appears. Symbols . Read First: Safety Information . Dangerous Voltage May Be Present . Double Insulation Overvoltage Installation Category per IEC 1010: CAT II Typical locations include; main wall outlets, local appliances, and portable equipment. CAT III Typical locations include switches in the fixed installation and equipment for industrial use permanently connected to the fixed installation.

Automatic Touch HoldaMode W Warning To avoid electric shock, do not use the Touch Holda mode to determine if a circuit with high voltage is dead. The Touch Holda mode will not capture unstable or noisy readings. The Touch Holda mode automatically captures and displays stable readings for all functions. + _ HOLD HOLD Momentary HOLD V _ RANGE + HOLD V Single Beep _ RANGE CAT CAT + HOLD V hc4f.eps When the meter captures new input, it beeps and a new reading is displayed. Note Stray voltages can produce a new reading. To exit the Touch Holda mode, press momentarily or turn the rotary switch. Bar Graph The bar graph shows readings relative to the full scale value of the displayed measurement range and indicates polarity. hc15f.eps Standby If the meter is on but is inactive for an hour (20 minutes in diode test), the display goes blank and displays four bar graph segments.
