IMPORTANT SAFETY INFORMATION
Read
and
understand
all of the instructions and
safety information in these operating instructions
before using this meter. Use the meter only as
specified in this manual; otherwise, the protection
provided by the meter may be impaired.
A
WARNING
statement identifies hazardous
conditions and actions that could cause bodily
harm or death.
WARNINGS
To avoid possible electric shock, personal injury or
death follow these guidelines:
• Do not use if meter appears damaged. Visually
inspect the meter to ensure case is not cracked
and back case is securely in place.
• Inspect and replace leads if insulation is dam-
aged, metal is exposed, or probes are cracked.
• Do not use meter if it operates abnormally as
protection maybe impaired.
• Do not use during electrical storms or in wet
weather.
• Do not use around explosive gas, dust, or vapor.
• Do not apply more than the rated voltage to the
meter.
• Do not use without the battery and the back case
properly installed.
• Remove the test leads from the meter before
removing battery cap.
• Do not attempt to repair this unit as it has no
user-serviceable parts.
• Disconnect power and discharge capacitors
before testing resistance, continuity, diodes,
capacitance or temperature.
• Replace battery as soon as low battery indicator
appears.
• Use the proper terminals, function and range for
your measurements.
To protect yourself, think "Safety First":
• Voltages exceeding 30VAC or 60VDC pose a
shock hazard so use caution.
• Use appropriate personal protective equipment
such as safety glasses, face shields, insulating
gloves, insulating boots, and/or insulating mats.

• Before each use:
- Perform a continuity test by touching the
test leads together to verify the functionality
of the battery and test leads.
- Use the 3 Point Safety Method. (1) Verify
meter operation by measuring a known
voltage. (2) Apply meter to circuit under
test. (3) Return to the known live voltage
again to ensure proper operation.
• Never ground yourself when taking electrical
measurements.
• Connect the black common lead to ground
before applying the red test lead to voltage.
Disconnect the red test lead from the voltage
first.
• Always work with a partner.
• When using the probes, keep fingers as far
behind the probe tips as possible.
Ranges & Accuracies:
AC Converter:
61-312 model is averaging
sensing, rms calibrated; 61-314 model is true rms
sensing.
Accuracy:
Accuracy is specified as +/-(a
percentage of the r a fixed amount) at
23°C±5°C (73.4°F ± 9°F), less than 75% relative
humidity.
Temperature Coefficient:
0.1 times the
applicable accuracy specification from 32°F to
64°F and 82°F to 122°F (0°C to 18°C ; 28°C to
50°C).
