ETEKCITY MSR-R500 User manual
Thank you for purchasing the Etekcity® MSR-R500
Digital Multimeter. Measure DC and AC voltage, current,
diode and audible continuity, and resistance with the
convenience of one single tool with built-in overload
protection.
Safe and Proper Usage
WARNING: TO AVOID THE RISK OF ELECTRIC
SHOCK OR THE DAMAGE OF THE MULTIMETER OR
OTHER EQUIPMENT, DO NOT CONNECT TO ANY
INPUT TERMINALS OF THE MULTIMETER THAT
MAY EXCEED 500V.
Read all the instructions provided in this manual.
Failure to comply with the instructions in the manual
and/or use of the device in ways other than the ones
mentioned in the manual may result in serious injury,
fire, and/or electrical shock. The person responsible for
this equipment must ensure that all users understand
the directions and adhere to them.
This meter complies with standard IEC61010: in
pollution degree 2, overvoltage category (CAT I 600V,
CAT II 300V) and double insulation.
CAT I: Signal level, special equipment or parts of
equipment, telecommunications, electronic, etc.
CAT II: Local level, appliance, PORTABLE EQUIPMENT
etc., with smaller transient overvoltages than CAT III.
Safety Operating Procedures
• Be sure to read, understand and comply with all the
instructions in this manual.
• Make sure the test leads are in a safe state. Keep
- 1 -
equipment out of humidity or moist environments.
• DO NOT use the meter if it is damaged or the case (or
part of the case) is removed. Look for cracks or
missing plastic. Check the insulation around the
connectors before use.
• DO NOT use the equipment in wet environments.
• Remove the test probes from the item of
measurement before changing the settings or
measurement functions on the multimeter.
• DO NOT apply the multimeter to voltages that may
exceed 500V.
• DO NOT measure voltages when the meter is set to
measure resistance (Ω).
• Always use the fuses of the correct type as specified
within the instructions to avoid any injury, electrical
shock, or risk of fire.
• DO NOT operate the meter around explosive gas,
vapor, or dust.
• When operating the test probes, keep your fingers
behind the finger guards.
• When making electrical connections, connect the
common test lead (black) before connecting the live
test lead (red). When disconnecting, disconnect the
live test lead (red) before disconnecting the common
test lead (black).
• Always remove the test leads before replacing the
battery within the multimeter or opening the battery
compartment.
• Inspect the condition of the test leads and the
multimeter for any damage before operating the
meter. Repair or replace any damage before use.
• Verify the meter’s operation by measuring a known
voltage before and after using the meter.
• DO NOT change the settings on the rotary switch
while the test leads are measuring a source of power.
• Use great care when making measurements if the
- 2 -
voltages are greater than 25VAC rms or 35VDC.
These voltages are considered to be a shock hazard.
• DO NOT operate the meter with the battery cover
removed or the case open.
• DO NOT remove the cover or open the case of the
meter without first removing it from the main power
source.
• DO NOT allow children to operate this device.
• USE a 9V DC battery when replacing the battery
within the device.
• Make sure to insert the battery under the correct
polarity indicated in the device.
• DO NOT use leaking batteries.
• DO NOT dispose old batteries in fire.
• Expired or damaged batteries can cause cauterization
on contact with skin. Always therefore, use suitable
hand gloves for protection in such cases.
• Disconnect circuit power and discharge all high
voltage capacitors before testing resistance,
continuity, diodes, or capacitance.
• Before measuring current, check the meter’s fuses
and turn off power to the circuit before connecting
the meter to the circuit.
• In the case the device is going to be unused for an
extended period of time, remove the battery before
storage.

Measurement Operation
DC Voltage Measurement
DC Voltage Ranges: 200mV, 2000mV, 20V, 200V, 500V
Input Impedance: 10MΩ
1. Plug the red test lead into the VΩmA terminal, then
plug the black test lead into the COM terminal.
2. Set the rotary switch to the appropriate
measurement in V range.
3. Connect the test leads to the object of measurement.
Hold them in place until the results on the display
stabilize.
4. When measurement is completed, disconnect the test
leads from the object of measurement.
NOTE
• If the value of voltage is unknown, use the maximum
measurement position (500V) and reduce the range
until proper readings are obtained.
• The LCD will display “OL” if there in an overload
within the selected range. Select a higher range to
obtain a correct reading.
• If the circuit impedance is less than or equal to 10kΩ,
the error is negligible (0.1% or less).
