Digital Multitester  (220-0204)        Operation      Faxback Doc. # 14076

WARNING:  To avoid electric shock, disconnect measuring terminals before
          removing battery.  Replace only with same type battery.  Open
          cabinet only when replacing battery.  Do not touch any inside
          area other than battery.

You'll need one 9-volt battery for 20 Megohm range, one "AA" penlight cell
for other resistance ranges.  We recommend our 230-0583/0553 for 9V, and
our 230-0582/0552 for "AA".  Remove the back case and install the
batteries in the correct compartment.  Observe the proper polarity.
Replace the back cover.  If you can't adjust the pointer for "0" on OHMS
scale, it's time for a new battery.  Replace the relevant battery with a
new one.  By the way, never leave weak or dead batteries in your unit.
They may leak damaging chemicals (even "leak-proof" type). Also, if you
are not going to use your unit for a week or more, remove the batteries.

For the most accurate readings, keep the meter lying flat on a non-
metallic surface.  Also, use a Range and Range Doubler setting that
results in a reading in the upper third of the meter scale.

Also, look at the scale from the point where the pointer and its
reflection on the mirror come together; else a reading error due to
parallax will result.

If the pointer does not normally rest exactly over "0" at the left side of
the scale, adjust the plaster screw in the lower center of the meter face
to bring the needle to "0".

Always observe correct test lead polarity when making DC measurements;
Black into (-) COM and Red into the (+) V-ohm-A (or (+) DC 1000V or
(+) DC 10A) jacks.

The maximum input limit for voltage and current measurement between
(+) V-ohm-A and (-) COM is 1000V AC, 250V DC and 500 mA DC.

Exercise extreme caution when measuring voltages of 150 and above.

When not in use, always leave the Range switch in the "OFF" position.

Use the Range Doubler as follows:

  For Resistance readings, always use the V-ohm-A position.

  When using the V-A/2 position for all other functions, divide the Range
  switch setting by 2 and read on an appropriate scale.  For example,
  Range set to 250 AC V and V-A/2 -- the range is 125 volts (250 divided
  by 2) and you should read the red scale, following the 0 to 125
  markings.  Another example:  lead in (-) COM and 10A with Range set to
  10A and V-A/2 -- the range is 5 amperes (10 divided by 2) and you should
  read the black scale, following the 0-50 markings.

TEST LEADS

Use only the same type of test leads as are supplied with your unit.
These test leads are rated for 1000 volts; replacements are available from
your local Radio Shack store.
