Data Hold; Diode Test; Relative Zero Mode; Non-Contact Voltage - Amprobe AM-540 Mode D'emploi

FEATURES

The multimeter designed for professional HVAC technicians. The AM-540 /
AM-540-EURmeasures a complete range of electrical parameters and features
key functions such as temperature, capacitance to check the motor startup
capacitors, micro amps for flame sensor troubleshooting, and a low pass filter
to take accurate measurements on variable frequency drives. With built
in flashlight, and non-contact voltage detection the AM-540 is the choice
multimeter for a professional HVAC technician. Safety rated to CAT IV 600V,
CAT III 1000V for the most advanced HVAC troubleshooting needs.
The Amprobe AM-550 / AM-550-EUR is a fully featured multimeter designed
for professional electricians who need to maintain service or troubleshoot
advanced electrical systems. True-rms sensing accurately measures voltage
on systems affected by harmonics; built in flashlight allows you to identify
wires while working in dark or dimly lit conditions, and non-contact voltage
detection allows for quick go-no-go checks without the need for an additional
tool. The AM-550 / AM-550-EUR also features dual input temperature
measurement, a low impedance function to detect stray voltage, and a low
pass filter to accurately take measurements on variable frequency drives.
Safety rated to CAT IV 600V and CAT III 1000V for use in the most industrial
applications.
