should be performed only by qualified
personnel.
Avoid direct exposure to sunlight to ensure
extended life of the Meter.
Do not place Meter in a strong magnetic field;
this may cause false readings.
Use only the batteries indicated in the
Technical Spec.
Avoid exposing batteries to humidity. Replace
batteries as soon as the low battery indicator
appears.
Please keep the original packing for future
shipping purposes (ex. Calibration)
After opening the box, check for any damage
during delivery.
Safety Symbols on the Meter
Important safety information, please refers
to the user manual
Earth ground
Indicates compliance with requirements for
double insulation

Important Safety Information
Never use the Meter to measure voltages that
might exceed 1000V DC/AC above earth
ground.
Always be careful when working with voltages
above 60V DC or 30V AC RMS. Keep fingers
behind the probe barriers while measuring.
Never connect the Meter leads across a
voltage source while the rotary switch is in
the resistance, diode or continuity mode.
Doing so can damage the Meter.
Inspect test leads and probes for cracks,
breaks or crazes on the insulation before
using the Meter.
Repair or maintenance should be
implemented by trained personnel.
Certification
CAT II: This meter has meet IEC1010-1
standard with an overvoltage category (10
00V CAT II) and pollution degree 2.
The Meter is compiled to EMC
requirements.

Using the Meter
Preparation
Fully plug the test leads into the input jacks. Red lead to
“VΩA+” input and black lead to “COM-“input.
Calibration of the scale is needed before making
measurement. Use a small size flat tip screwdriver to
adjust the black knob located in the center of the Meter,
next to the Dawson logo. The needle on the scale should
align with “0” on the left side of the scale.
The “ ” symbol next to the input lead
shows that the input voltage or current should
not exceed the specified value in order to
protect the internal circuit from damage.
Turn the rotary switch to the required
function and range to be measured.
Choose the highest range when the value to
be measured is unknown.
When making connection, connect the
common test lead first and then the powered
test lead.
Remove the charged test lead first when
disconnecting.

Reading the Scale
General
Make sure to align the needle with the scale.
Resistance (Ohms - Ω)
Use the top scale (Green) to read resistance.
If the meter is set to X10, multiply the resistance value by
10, and in x1K multiply the resistance value by 1000.
DC Voltage (V DC)
Use the middle scale (Black). To read of the
measurement, first match the dial range setting to the
highest number on the scale to find out the according
scale.
