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
2.1 Battery Installation
Before changing batteries: set the switch to OFF, disconnect the
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.

2.3 Measurements
2.3.1 DC Current
For safety, disconnect the measurement leads before performing this
operation.
The clamp must be positioned around a single conductor in a circuit;
otherwise the measurement will be invalid.
To maximize accuracy, center the jaws around the conductor.
Figure 5
1. Set the switch to .
2. Press the trigger to open the clamp.
3. Place the clamp around the conductor to be measured and release
the trigger. Ensure the clamp is completely closed.
4. Read the result on the LCD.

12 Clamp-On Meter Model 505
2.3.2 AC Current
For safety, disconnect the measurement leads before performing this
operation.
The clamp must be positioned around a single conductor in a circuit;
otherwise the measurement will be invalid.
To maximize accuracy, center the jaws around the conductor.
Figure 6
1. Set the switch to .
2. Press the trigger to open the clamp.

to the COM input terminal.
3. Touch the lead probe tips to the AC circuit to be measured.
4. Read the result on the LCD.
If the meter detects voltage >30VAC, the (hazardous) icon appears on
the LCD. In this case, immediately remove the probes from the circuit
under test. Also remove the probes from the circuit if the reading
displays OL.

Clamp-On Meter Model 505 17
2.4 ∆ ZERO Mode
∆ZERO mode enables you to view a measurement as the difference between it
and a selected “reference” value.
To enable this mode, press the ∆ZERO button after making a measurement.
The measurement becomes the reference, and will be subtracted from
subsequent measurements. This difference will then be displayed on the LCD.
When the meter is in this mode, the ∆symbol appears on the LCD.
Press ∆ZERO a second time to exit this mode.
2.5 HOLD Function
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.
When the meter is in this mode, the word PEAK appears on the LCD.
Press PEAK a second time to exit this mode.
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
when turning the instrument ON.
