results from your instrument and for your safety, read the enclosed operating
instructions carefully and comply with the precautions for use. This instrument is
compliant with safety standard IEC 61010- 2-032; the leads are compliant with
IEC 61010-2-031 for voltages up to 600 V in category III. Failure to observe the
safety instructions may result in electric shock, fire, explosion, or destruction of
the instrument and of the installations.

PRECAUTIONS FOR USE
These safety instructions are intended to ensure the safety of persons and
proper operation of the device.
The operator and/or the responsible authority must carefully read and clearly
understand the various precautions to be taken in use.
If this instrument is used other than as specified, the protection it provides
may be compromised, thereby endangering you.
Do not use the instrument in an explosive atmosphere or in the presence of
flammable gases or fumes.
Do not use the instrument on networks of which the voltage or category
exceeds those mentioned.
Do not exceed the rated maximum voltages and currents between terminals
or with respect to earth.
Do not use the instrument if it appears to be damaged, incomplete, or not
properly closed.
Before each use, check the condition of the insulation on the leads, housing,
and accessories. Any element of which the insulation is deteriorated (even
partially) must be set aside for repair or scrapped.
Use leads and accessories rated for voltages and categories at least equal
to those of the instrument. If not, an accessory of a lower category lowers
the category of the combined clamp + accessory to that of the accessory.
Observe the environmental conditions of use.
Do not modify the instrument and only use factory replacement parts.
Repairs and adjustments must be done by approved qualified personnel.
Replace the batteries as soon as the symbol appears on the display of
the unit. Disconnect all leads before opening the battery compartment cover.
Use personal protective equipment when conditions require.
Keep your hands away from the unused terminals of the instrument.
When handling the test probes, alligator clips, and clamp ammeters, keep
your fingers behind the physical guard.
As a safety measure, and to avoid repeated overloads on the inputs of the
device, configuration operations should only be performed when the device
is disconnected from all dangerous voltages.

2 OPERATION
Before changing batteries: set the switch to OFF, disconnect the
2.1 Battery Installation
measuring leads, and remove the clamp from the circuit under
measurement.
1. Using a screwdriver, remove the battery compartment cover from the
back of the housing (see Figure 4).
2. Insert the two supplied 1.5V AA batteries, observing polarities.
3. Replace the battery compartment cover and screw it onto the housing.
Figure 4
2.2 Instrument Check
Start the meter by turning the rotary switch to any setting other than OFF.
Observe the LCD and ensure all segments are displayed (see Figure 2).
Turn the switch to the (continuity) setting. The LCD should display
OL.
Connect the two test leads to the instrument and touch the tips together. The
short-circuit buzzer should sound.
Turn the switch to a voltage setting (either or ) and check a known
voltage (for example a battery). Ensure the displayed voltage reading is
correct.
If all previous steps function normally, the meter is ready for operation.

Pressing the HOLD button “freezes” the measurement on the LCD. In this mode,
the word HOLD appears on the LCD.
Press HOLD again to exit this mode and resume updating the measurement
display.
2.6 PEAK Mode
In PEAK mode the instrument only updates the LCD when the instantaneous
measurement exceeds the displayed value.
To enable this mode, press the PEAK button for >2 seconds. The measurement
remains on the screen until an instantaneous measurement is made that
exceeds the displayed value, at which point the LCD displays the new
measurement.

In PEAK mode, pressing HOLD has no effect.
2.7 Auto Shutdown
By default, the Model 505 automatically turns OFF after 20 minutes of inactivity.
The instrument can then be re-activated by either pressing the HOLD button or
changing the switch setting.
When the meter is in this mode, the icon appears on the LCD.
To disable the Auto Shutdown feature, press and hold down the HOLD button

4 MAINTENANCE
Except for the batteries, the instrument contains no parts that can be
replaced by personnel who have not been specially trained and
accredited. Any unauthorized repair or replacement of a part by an
"equivalent" may gravely impair safety.
4.1 Cleaning
Disconnect the instrument completely and turn the rotary switch to OFF.
Use a soft cloth, dampened with soapy water.
Rinse with a damp cloth and dry rapidly with a dry cloth or forced air.
Do not use alcohol, solvents, or hydrocarbons.
Keep the clamp jaws as clean as possible.

REPAIR AND CALIBRATION
To ensure that your instrument meets factory specifications, we recommend
that it be submitted to our factory Service Center at one-year intervals for
recalibration, or as required by other standards or internal procedures.
For instrument repair and calibration:
You must contact our Service Center for a Customer Service Authorization
number (CSA#). This will ensure that when your instrument arrives, it will be
tracked and processed promptly. Please write the CSA# on the outside of
the shipping container. If the instrument is returned for calibration, we need
to know if you want a standard calibration, or a calibration traceable to
N.I.S.T. (includes calibration certificate plus recorded calibration data).
(Or contact your authorized distributor)
Costs for repair, standard calibration, and calibration traceable to N.I.S.T. are
available.
NOTE: All customers must obtain a CSA# before returning any
instrument.
TECHNICAL AND SALES ASSISTANCE
If you are experiencing any technical problems, or require any assistance
with the proper operation or application of your instrument, please call, mail,
fax or e-mail our technical support hotline:
NOTE: Do not ship instruments to our Foxborough, MA address.
