3. TERMS IN THIS MANUAL A WARNING Identifies conditions and actions that could result in serious injury or even death to the user A CAUTION Identifies conditions and actions that could cause damage or malfunction in the instrument WARNING To reduce the risk of fire or electric shock do not expose this product to rain or moisture The meter is intended only for indoor use To avoid electrical shock hazard observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms These voltage levels pose a potential shock hazard to the user Inspect test leads connectors and probes for damaged insulation or exposed metal before using the instrument If any defects are found replace them immediately Do not touch test lead tips or the circuit being tested while power is applied to the circuit being measured To avoid accidental short circuit of bare un insulated hazardous live conductors or bus bars switch them off before insertion and removal of the current clamp jaws Contact with the conductor could result in electric shock Keep your hands fingers behind the hand finger barriers that indicate the limits of safe access of the meter and the test leads during measurement A CAUTION Disconnect the test leads from the test points before changing meter functions INTERNATIONAL ELECTRICAL SYMBOLS A Caution Refer to the explanation in this Manual Caution Risk of electric shock Earth Ground
4. AC voltage To activate the Hz Frequency function press the Hz button momentarily Note 400 0 range is designed with 1000M high input impedance for least current drain in measuring small signals and can cope better with most commercially available voltage output transducers adapters The non zero display reading is normal when the meter inputs are open circuit which will not affect actual measurement accuracy The meter will show close to zero reading when the inputs are shorted Open input is actually a floating condition which is not a zero volt input condition Note Hz input sensitivity varies automatically with function range selected while activating the Hz function Lowest range has the highest sensitivity and the highest range has the lowest sensitivity Activating the Hz function WHILE measuring the specific function signal auto ranging can automatically select the best sensitivity range to avoid electrical noise that may cause unstable Hz reading However if the Hz reading shows zero due to insufficient sensitivity activate the Hz function BEFORE measuring the specific function signal The meter is then in the lowest range and can select the highest sensitivity range Q Resistance and al Continuity functions Inputs are made through the test leads terminals Move the slide switch to the position The unit defaults at Q Press SELECT button momentarily to select Continuity function which is convenient
