Frequently Asked Questions DT70   How does the non-contact voltage detection work? What is hi voltage indication? What is relative mode? Is it possible to determine the maximum current draw on a line that has loads that vary? Can I measure motor start up current with the DT70 clamp-on tester? Can I test the run and start capacitors on motors? Do I need an adapter to measure temperature with the DT70? What is the value of having an analog bargraph display? Is it possible to measure AC amps on a device that uses a power cord?   How does the non-contact voltage detection work? This feature allows you to detect the presence of voltage without contacting the circuit with the test leads. By pressing the NCV button and holding the jaw close to the wire or circuit, the meter will inform you both audibly and visually if the circuit is live.   What is hi voltage indication? High voltage indication is an audible and visual safety alert informing you the test leads are in contact with a voltage greater than 30V AC or DC.   What is relative mode? Relative mode allows you to perform measurements relative to a stored value. For example, when performing a low resistance measurement, first touching the test prods together and pressing the relative button will subtract the lead resistance from subsequent measurements.   Is it possible to determine the maximum current draw on a line that has loads that vary? By activating the min/max mode on the DT70 it will record the minimum and maximum current measured. This is helpful when trying to see what the maximum load draw is as devices turn on and off.   Can I measure motor start up current with the DT70 clamp-on tester? Yes, the DT70 has a peak hold function that allows motor start up current to be captured.   Can I test the run and start capacitors on motors? The DT70 has the ability to measure capacitors up to 40,000 microfarads in size.   Do I need an adapter to measure temperature with the DT70? An adapter is not needed to perform temperature tests with the DT70. The DT70 accepts K-type thermocouple probes with a sub-mini connector.   What is the value of having an analog bargraph display? The analog bargraph allow you to see rapid signal fluctuations occurring too fast to be seen on the digital display. Meters without this feature are unable to show the presence of rapidly fluctuating inputs.   Is it possible to measure AC amps on a device that uses a power cord? Yes, to accomplish this you can use the line splitter (LS59). AC amps must be measured by isolating a single wire and the LS59 line splitter does this without damaging the power cord.
