Measurement Category II {CAT I} lis for measurements performed on cultural directly connected to low voltage installation. Examples are measurements on household appliances, portable tools and similar equipment. A A warning: Read Ba fore Using « To avoid possible electrical shack or parsons! Injury, follow these Instructions and use the Meter only as specified In this manual. « Do nat use the Mater or test leads if they appear damaged, or If the Meter is not operating property.
FEATURES AM-520/ AM-520-EUR is designed for VAC 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 / AM-520-EUR measures a complete range of electrical parameters and features a built in flashlight, a “third hand* probe holder and Voltmeter non-contact voltage detection. Safety rated to CAT Ill 600V.
MAKING MEASUREMENT AA 1. Usa 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 ail 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 A Relative zero made Manual ar Auto range switching. The default setting RANGE Is Auto ranging, press to switch to manual ranging {delectable resolutions). Press for 2 sec to rectum to auto ranging MAX MIN | Maximum / minimum reading memory. = Flash light Tress X to enable the function when at relevant rotary switch function. Auto Power OFF Auto power off: approx. 15 minutes. When the Meter [5 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. A A\o 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 cultural when the test leads ara connected to the current terminals. 4.
Measuring Resistance Disconnect cultural power and discharge all high-voltage capacitors before testing resistance. Note: On a higher resistance measurement (>1MI1), the measurement may take a few seconds to get stable reading.
Measuring Continuity I A\ Disconnect circuit power and discharge all high-voltage capacitors before testing continuity. 3 HOLE 25ec s Meet Measuring Diode I A\ Disconnect circuit power and discharge all high-voltage capacitors before testing diode
Measuring Capacitance Disconnect circuit parer and discharge all high-voltage capacitors before testing capacitance Measuring Frequency To avoid personal injury or damage to the Meter, do not apply voltage higher than 600V.
Measuring Temperature avoid personal injury or damage to the Meter, do not apply the temperature probe to any live conductive parts. 2. Temperature sensor K type thermonuclear is suitable for temperature measurement below 230°C Measurement steps: Step 1: Tum the rotary switch 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 insulated 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 500V 4. Before and after hazardous voltage measurements, test the Meter by approaching to a known source such as a line AC voltage or outset to determine proper operation. See helot 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 @ function Step 2: short-circuit */V/Q/MHz terminal and mama terminal. Resistance reading = 1MQ: the fuse is OK Resistance reading "OL": the fuse is open.
Except for the replacement of the battery, repair of tha mater should ba performed only by a Factory Authorized Service Center or by other qualified instrument service personnel. The from 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, Ga saline or chlorinated solvents for cleaning.
