welcome to this overview of the RS pro
iit 1500 insulation tester the RS pro
iit 1500 insulation tester provides
insulation test voltages from 50 volt
through 2000 volts you can also do AC
and DC voltage measurements and
resistance measurements the RS Pro r8t
1500 comes with several included
accessories the first of these is the
remote test probe this test probe allows
you to activate the test with the remote
test button by using the test button on
the probe you don't need to reach across
to the test button on the meter it also
has a cap which provides protection for
the long sharp tip to help prevent any
possible shorting in high energy cabinet
the included test leads are made of nice
soft flexible silicone and a good strain
relief at the connectors that enter the
meter
there are also test probes that connect
to the test leads that have very good
finger grip and protection again to
prevent shorting that only expose a
short portion of the test probe the
included crocodile clips allow you to
connect two cables or wiring and then
allow you to operate hands-free while
doing insulation testing the included
manual is written in several languages
and contains very clear diagrams to
explain the functionality and operation
of the meter there is a magnetic hanging
strap which connects to the back of the
meter this will allow you to hang the
meter in any metal cabinets to give you
hands-free operation the RS pro iit 1500
has a nice large 4000 count display it
has an insulation test range of 0.001
mega ohm to 20 Giga ohm it's got
insulation test voltages of 50 100 250
500 and a thousand volts it can perform
polarization index and dielectric
absorption ratio calculations the meter
selector allows you to switch between
voltage resistance and your insulation
resistance test voltages the voltage
function can be very helpful to ensure
that your circuits are de-energized
before doing any
testing the meter will Auto sense
whether you have an AC or a DC voltage
present the blue function button will
allow you to select a low-pass filter
simply selecting the blue button while
in the voltage selection will enable the
low-pass filter and the low-pass filter
icon will appear in the display to
perform any insulation resistance test
you simply select the dial to one of
those voltage levels that you want to
test that this meter also allows you to
store and recall any readings that you
obtain from your test you have a lock
feature which allows you to lock the
test button so that you don't have to
hold the test button while performing
longer tests the meter also has a
comparison feature with a pass/fail so
if you're doing multiple tests and wants
a quick pass fell on whether they're
passing a certain resistance level you
simply push the compare and you can
switch between various resistance levels
here it's at a hundred kilo ohm two
hundred kilo ohm five hundred kilo ohm
and 1 mega ohm to make a ohm five mega
ohm 10 mega ohm 20 mega ohm and 50 mega
ohm it'll then return to the hundred
kilo ohm in this example I'm testing
some wiring to see the passes at the two
mega ohm mark I simply push and hold the
test button the results of 55 mega ohm
passes and lights up the green path led
the results or readings are held on the
screen so you have time to make a note
of them you can also push the store
button to store them into memory that
test can be terminated by pushing the
test button once again if we then hold
down the store button which pulls up the
recall our result is then pulled up and
we can see the result the blue function
button and the comparison button with
the two areas above them will allow you
to browse through any other readings
that you have saved in the memories to
perform installation tests with the
supplied remote probe we simply install
one of the test leads into the common
connector
and that I connected up to one of your
wiring points or switches that you're
going to test you then simply install
the remote connection probe into the
special connector to execute the
installation test you can use the remote
test switch on the probe or on the meter
the test will be active for as long as
you hold down the test switch it will
then stop once you release the test
switch or you can use a lock button so
that you can activate the test with a
momentary push of the test button and
then stop it afterwards at this point
I'm going to do an installation test at
a hundred volts using a probe with a
remote test button I can then release
the test button and the result is held
on the display to conduct an insulation
resistance test hand three simply
connect both of the test leads and the
crocodile clips to the cables that you
want to test you can then simply hold
down the test button once you've
selected your test voltage light will go
red showing you doing the test and your
result will be shown once you've made a
note of the reading you can simply push
the test button to exit that result to
execute a longer test like the
dielectric absorption ratio or daar test
have your crocodile clips connected
select your test voltage and then hold
down the lock button this will initially
display the t-i or pie icon the
polarization index test push once again
to get to the dart test push the test
button to initiate the test on the
display you'll see D test voltage and
then the insulation resistance reading
which will probably change over time if
you push the blue function button you
will see the time remaining for the dart
test
once the test completes the result will
be displayed on the screen you can
simply push the blue function button
which will show you the reading at 30
seconds and then the reading at 1 minute
if you want to save these simply push
the store buttons they are stored in
memory location 1 to exit any PI or PI
or data simply hold down the lock button
you'll note that the icon then
disappears to execute a longer manual
test simply push the lock button once
you'll see the lock annotation appear on
the screen and then push the test button
once you've selected your test voltage
you then don't need to hold down the
test button and you can allow that test
to execute as long as you'd like once
you're happy with the duration of the
test simply push the test button again
to stop the test and the end result will
be shown on the display the lock
function is then disabled for any
further testing you'd have to push a
lock button again to enter a locked mode
for any further tests the meter also has
a very handy backlight which is
activated by a sensor at the top of the
display
