Instruction Manual
Read First: Safety Information
Understand and follow operating instructions
carefully. If this tester is not used in a manner
specified by IDEAL, protection provided by the
product may be impaired.
WARNINGS
To avoid possible electric shock, personal injury or
death follow these instructions:
• 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 damaged, metal is exposed, or probes are cracked.
Pay particular attention to the insulation surrounding the connector.
• 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 to avoid false readings.
• Use the proper terminals, function and range for
your measurements.
• Comply with local and national safety
requirements, including the use of appropriate
personal protective equipment.
CAUTION:
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 or
neutral before applying the red test lead to
potential 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: 61-340 model is averaging
sensing, rms calibrated; 61-342 model is true rms
sensing.
Accuracy: Accuracy is specified as +/-(a
percentage of the reading + 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).
