Safety Information

WARNING

Understand and follow operating instructions carefully.

Use the meter only as specied in this manual; otherwise,the

protection provided by the meter may be impaired.

This identies hazardous conditions and actions that could

cause BODILY HARM or DEATH. To avoid possible danger,

follow below guidelines.

• Use the meter only as specied 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

specied 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 identies 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.

The following sections describe how to take measurements

with the meter.

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

o󰀨set) 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. Dene as below :

For best accuracy when measuring the DCmV, touch the

probe tips together and read the DC o󰀨set. 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

specied 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 specications.

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.
