SYMBOLS X � B F Caution! Risk of electric shock. T The equipment is protected by double insulation or reinforced insulation J Earth (Ground) Caution! Refer to the explanation in this Manual Alternating Current (AC) Direct Current (DC) Audible tone Battery � Complies with European Directives Conforms to relevant Australian standards ) = Canadian Standards Association (NRTL/C) Do not dispose of this product as unsorted municipal waste. Contact a qualified recycler.
Measurement Category II (CAT II) is for measurements performed on circuit directly connected to low voltage installation. Examples are measurements on household appliances, portable tools and similar equipments. X�Warning: Read Before Using • To avoid possible electrical shock or personal injury, follow these instructions and use the Meter only as specified in this manual. • Do not use the Meter or test leads if they appear damaged, or if the Meter is not operating properly.
FEATURES AM-520 is designed for HVAC applications with key functions such as temperature, micro amps used for flame sensor troubleshooting, as well as and capacitance to check the motor startup capacitors. The AM-520 measures a complete range of electrical parameters and features a built in flashlight, a “third hand” probe holder and VoltTect non-contact voltage detection. Safety rated to CAT III 600V. AM-530 is the fully-featured multimeter of choice for the professional electrical contractor.
MAKING MEASUREMENT X� 1. Use the proper function and range for measurements. 2. To avoid possible electrical shock, personal injury or damages to the Meter, disconnect circuit power and discharge all high-voltage capacitors before testing resistance and diode. 3. Connecting test leads: • Connect the common (COM) test lead to the circuit before connecting the live lead; • After measurement, remove live lead before removing the common (COM) test lead from the circuit 4.
REL Relative zero mode RANGE Manual or Auto range switching. The default setting is Auto ranging, press to switch to manual ranging (selectable resolutions). Press for 2 sec to return to auto ranging. MAX/MIN Maximum / minimum reading memory. Flash light Press to enable the function when at relevant rotary switch function. Auto Power OFF Auto power off: approx. 15 minutes. When the Meter is in auto power off mode, press any button to resume normal operation.
Measuring AC and DC Current Press SELECT button to select AC or DC current measurement function. X�To avoid personal injury or damage to the Meter: 1. Do not attempt to make an in-circuit current measurement when the open-circuit potential to earth ground exceeding AC 600V or DC 600V 2. Switch to proper function and range for your measurement. 3. Do not place the test probe in parallel with a circuit when the test leads are connected to the current terminals. 4.
RL RL Measuring Resistance X� Disconnect circuit power and discharge all high-voltage capacitors before testing resistance. Note: On a higher resistance measurement (>1Me), the measurement may take a few seconds to get stable reading.
Measuring Continuity X� Disconnect circuit power and discharge all high-voltage capacitors before testing continuity. Measuring Diode X� Disconnect circuit power and discharge all high-voltage capacitors before testing diode.
Measuring Capacitance X� Disconnect circuit power and discharge all high-voltage capacitors before testing capacitance. Measuring Frequency X� To avoid personal injury or damage to the Meter, do not apply voltage higher than 600V.
Measuring Temperature °C / °F X� 1. To avoid personal injury or damage to the Meter, do not apply thetemperature probe to any live conductive parts. 2. Temperature sensor K type (nickel-chromium/nichrosi) thermocouple is suitable for temperature measurement below 230°C (446°F). Measurement steps: Step 1: Turn the rotary switch to °C or °F position. The display will show “OL”. Step 2: Connect the temperature probe (K type) to the Meter and to the surface to be measured.
Non-Contact Voltage Sensing 1. To avoid personal injury or damage to the Meter, do not test on uninsulated high voltage wires. 2. Buzzer will sound and screen will display “OL” when sensing AC voltage between 90V and 600V 3. Do not test on hazardous live wires higher than AC 600V 4. Before and after hazardous voltage measurements, test the Meter by approaching to a known source such as a line AC voltage or outlet to determine proper operation. See below figure.

MAINTENANCE AND REPAIR If the Meter fails to operate, check battery, test leads, etc., and replace as necessary. Double check the followings: 1. Replace the fuse or battery if the meter does not work. 2. Review the operating instructions for possible mistakes in operating procedure. Quick check on 0.5A FUSE: Step 1: Turn the rotary switch to Ω function. Step 2: short-circuit E/V/Ω/Hz terminal and mA/μA terminal. Resistance reading ≤ 1MΩ: the fuse is OK Resistance reading “OL”: the fuse is open.
Except for the replacement of the battery, repair of the meter should be performed only by a Factory Authorized Service Center or by other qualified instrument service personnel. The front panel and case can be cleaned with a mild solution of detergent and water. Apply sparingly with a soft cloth and allow to dry completely before using. Do not use aromatic hydrocarbons, Gasoline or chlorinated solvents for cleaning.
