Frequency functions Inputs are made through the test leads terminals Slide switch on defaults at DC voltage Press SELECT button momentarily to select AC voltage Press the Hz push button momentarily to activate Hz Frequency function in the following slide switch functions DCV amp ACV via the test leads ACA via the jaw clamp 6 Note DC 400 0mV range is designed with 1000MQ 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 which 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
