Reading the Scale

Refer to this diagram while following the directions in the 

Operation

 section.

The Accuracy Mirror

The Accuracy Mirror is used to insure that the meter’s pointer is being read

straight, ensuring accuracy.  Simply make sure that the meter is angled so that, when
reading it, the reflection of the pointer is hidden under the pointer.  The pointer above
is being viewed at an angle, so the reflection is visible.

Note:

Although on some meters a decibel (db) scale is shown, this meter does not
have available the equipment to test sound decibel levels.

Warning:

Electric shock can cause DEATH or SEVERE PERSONAL INJURY.

Never touch exposed conductors of electricity with

fingers, hands or any other body part.

Operation

DC Voltage Measurements

Measure DC voltages up to 1,000 DCV.

1.

Turn the Range Selector Switch to 1000 DCV.

Always start with the highest range if the voltage is unknown.

2.

Plug the red lead into the + Jack. Plug the black lead into the -Com Jack.

3.

Carefully touch the appropriate exposed conductors with the tips of the probes
to measure the voltage (not amperes).

4.

Read measurement.  If the needle moves in the opposite direction, then the
probes are connected incorrectly.  Reverse the probes’ locations.

If the voltage is less than 250 volts, set the Range Selector Switch to the
next lower range until the meter pointer is mid-range on the scale.

5.

When testing is complete, remove Test Leads and store them and the meter
in a safe, dry location.
