1. 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.
2. 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.
3. 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.
4. 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
270 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.
5. Can I measure motor start up current
with the TPI 270 clamp-on tester?
Yes, the 270 has a peak hold function
that allows motor start up current to be
captured.
6. Can I test the run and start
capacitors on motors?
The 270 has the ability to measure
capacitors up to 40,000 microfarads in
size.
7. Do I need an adapter to measure
temperature with the 270?
An adapter is not needed to perform
temperature tests with the 270. The 270
accepts K-type thermocouple probes
with a sub-mini connector.
8. 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.
9. Is it possible to measure AC amps
on a device that uses a power cord?
Yes, to accomplish this you can use the
TPI line splitter (A202). AC amps must be
measured by isolating a single wire and
the A202 line splitter does this without
damaging the power cord.
