Safety Information
WARNING
Understand and follow operating instructions carefully.
Use the meter only as specied in this manual; otherwise,the
protection provided by the meter may be impaired.
This identies hazardous conditions and actions that could
cause BODILY HARM or DEATH. To avoid possible danger,
follow below guidelines.
• Use the meter only as specied in this manual or the
protection by the meter might be impaired.
• Never operate the meter with the cover removed or the
case open.
• To avoid false readings that can lead to electric shock and
injury, replace battery as soon as low battery indicator.
• Use caution with voltages above 30VAC rms, 42VAC peak,
or ±30VDC. These voltages pose a shock hazard.
• When using test leads or probes, keep your ngers behind
the nger guards.
• Remove test lead from meter before opening the battery
door or meter case.
• Always use proper terminals, switch position, and range for
measurements.
• Do not apply more than the rated voltage, as marked on
meter, between terminals or between any terminal and
earth ground.
• Do not use the High Frequency Rejection (Low Pass
Filter) option to verify the presence of hazardous voltages.
Voltages greater than what is indicated may be present.
First, make a voltage measurement without the lter to
detect the possible presence of hazardous voltage. Then
select the lter function.
• To avoid possible electric shock or personal injury, never
attempt an in-circuit current measurement where the open
circuit potential to earth is greater than 1000V.
• Replace the fuse as soon as the indicator (FUSE) appears.
• Only replace the blown fuse with the proper rating as
specied in this manual.
• Do not use the meter around explosive gas, vapor or dust.
• To reduce the risk of re or electric shock do not expose
this product to rain or moisture.

506/506B EN
• Do not attempt a current measurement when the open
voltage is above the fuse protection rating. Suspected
open voltage can be checked with voltage function.
• Never attempt a voltage measurement with the test lead
inserted into the A input terminal.
• Disconnect the test leads from the test points before
changing the position of the function rotary switch.
• Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes, or
capacitance.
• Always use proper terminals, switch position, and range for
measurements.
• Do not use the LoZ mode to measure voltages in circuits
that could be damaged by this mode’s low impedance.
• Replace the fuse as soon as the indicator (FUSE) appears.
• Never connect a source of voltage with the function rotary
switch in resistance, diode, continuity, and capacitance
position.
• Never set the meter in current function to measure the
voltage of a power supply circuit in equipment that could
result in damage the meter and the equipment under test.
This identies conditions and actions that could DAMAGE
the meter or equipment under test. To avoid possible
damage, follow below guidelines.

Making Basic Measurements
When turn the power on, press the function button to
execute the below options.
• When connecting the test leads to the DUT (Device Under
Test), connect the common test lead before connecting the
live lead. When removing the test leads, remove the test
live lead before removing the common test lead.

Measuring AC and DC Voltage
Make dB measurement
This meter have true rms readings, which are accurate
for distorted sine waves and other waveforms (with no dc
oset) such as square waves, triangle waves, and staircase
waves.
The ranges of measuring voltage are 40mV, 400mV, 4V,
40V, 400V and 1000V. To select the mV range, turn the
rotary switch to mV position.
The meter is capable of displaying voltage as a dB value, either
relative to 1 milliwatt (dBm), a reference voltage of 1 volt (dB).
A dBm measurement must use a reference impedance (600Ω)
to calculate a dB value based on 1 milliwatt. A dB measurement
uses a 1 volt reference voltage to compare the present
measurement against. Dene as below :
For best accuracy when measuring the DCmV, touch the
probe tips together and read the DC oset. If necessary, you
can use the relative (Δ) mode to automatically subtract this
value.

Measuring Voltage in LoZ Mode
To use dB or dBm function, turn the rotary switch to ACV or
ACmV position. Then move the blink cursor of menu to
dB or dBm position, and press the ENTER button to enter
function.
Press the CANCEL button to exit function.
Caution
• Do not use the LoZ mode to measure voltages in circuits
that could be damaged by this mode’s low impedance.
To eliminate ghost voltages, the meter’s LoZ mode presents
a low impedance across the leads to obtain a more accurate
measurement. The ranges of measuring LoZ voltage
are 400V and 1000V. In this mode, meter will automatic
measure input signal which is AC or DC and determine
range.
To use the LoZ mode, turn the rotary switch to LoZ position.
Measuring AC and DC Current
• Always use proper terminals, switch position, and range for
measurements.
• To avoid possible electric shock or personal injury, never
attempt an in-circuit current measurement where the open
circuit potential to earth is greater than 1000V.
• Only replace the blown fuse with the proper rating as
specied in this manual.
WARNING

506/506B EN
Caution
• Replace the fuse as soon as the indicator (FUSE) appears.
To measure current, you must break the circuit under test,
thenplace the meter in series with the circuit.
The ranges of measuring current are 40mA, 400mA, 4A and
10A. AC current is displayed as an rms value. Insert the
black lead into the COM terminal. For currents less than 400
mA, insert the red lead into the mA terminal. For currents
above 400 mA, insert the red lead into the A terminal.
You can press the function (yellow) button to select current
measurement function.
Measuring Frequency
The meter measures the frequency of a voltage or current
signal by counting the number of times the signal crosses a
threshold level each second.
This function only can be operated in AC voltage and current
measurements. The ranges of measuring frequency are
400Hz,4kHz, 40kHz and 100kHz.
If a reading shows as 0 Hz or is unstable, the input signal
may be below or near the trigger level. The detail of
frequency trigger level refer to the electrical specications.
To use the frequency function, press function (yellow) button
to select measurement function.

506/506B EN
Make Peak-Hold Measurement
The Peak-Hold mode records wave peak maximum and
minimum input values. Response time of Peak-Hold is 10us.
To use the Peak-Hold mode, press the P-HOLD button to
enable the Peak-Hold mode in the AC or DC measurements.
In this mode, press P-HOLD button to select peak MAX or
MIN value. Press > 1 sec to disable the Peak-Hold mode.
For square wave, use the peak-hold mode in the DC
measurements.
Make High Frequency Rejection Measurement
• Do not use the High Frequency Rejection (Low Pass Filter)
option to verify the presence of hazardous voltages.
Voltages greater than what is indicated may be present.
First, make a voltage measurement without the lter to
detect the possible presence of hazardous voltage. Then
select the lter function.
The High Frequency Rejection mode equip a low pass lter
in the AC measurements. The cut-o frequency (-3dB point)
of low pass lter is 800Hz.
To use the HFR mode, press the HFR button to equip a low
pass lter in the AC measurements.
