Introduction

Congratulations on your purchase of Extech model MM560 or MM570

digital multimeter. Properly used, this meter will provide many years of

reliable service.

MultiMaster™ Meters provides high resolution, high accuracy, true rms

measurements of AC Voltage and Current, DC Voltage and Current,

AC+DC, Resistance, Frequency, Capacitance, Duty Cycle, dBm, Peak,

%4-20, Diode, and Continuity. The MultiMaster™ also offers RS-232 PC

Interface data acquisition capabilities as an option. Model MM570 offers

dual input Temperature measurements and very wide bandwidth.

Safety Precautions

1. Improper use of this meter can cause damage, shock, injury or death.

Read and understand this users manual before operating the meter.

2. Make sure any covers or battery doors are properly closed and

secured.

3. Always remove the test leads before replacing the battery or fuses.

4. Inspect the condition of the test leads and the meter itself for any

damage before operating the meter. Repair or replace any damage

before use.

5. To reduce the risk of fire or electric shock, do not expose this product

to rain or moisture.

6. Do not exceed the maximum rated input limits.

7. Use great care when making measurements if the voltages are

greater than 25VAC rms or 35VDC. These voltages are considered a

shock hazard.

8. Always discharge capacitors and remove power from the device

under test before performing Capacitance, Diode, Resistance or

Continuity tests.

9. Remove the battery from the meter if the meter is to be stored for long

periods.

10. To avoid electric shock, do not measure AC current on any circuit

whose voltage exceeds 1000V AC.

11. Voltage checks on electrical outlets can be difficult and misleading

because of the uncertainty of connection to the electrical contacts.

Other means should be used to ensure that the terminals are not

"live".

12. If the equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be

impaired.

13. The product is intended only for indoor use.
