Ideal Electrical Test-Pro Digitalmultimeter 340-Serie Digital-Multimeter, DMM, 61-340 データシート

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.

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 dam-

aged, metal is exposed, or probes are cracked.
Pay particular attention to the insulation sur-
rounding 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.

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).
