Volts AC (VAC) True RMS (50-400Hz)
Test power lines (120 to 480VAC), test 24VAC going to controls and test
for transformer failure.
Ranges:
1000mV, 10V, 100V, 750V

Volts DC (VDC)
Select VDC and measure DC voltages on circuit boards on more
advanced HVACR systems and logic control boards.
Ranges:
1000mV, 10V, 100V, 1000V
Resolution:
0.1mV
Accuracy:
±(0.5% + 5)
Input Impedance:
5MΩ
Overload Protection:
1000VDC or 750VAC rms
Non Contact Voltage (NCV)
Use NCV to check 24VAC from a thermostat or live voltage up to 600VAC.
Always test a known live source before using. A segment graph and RED
LED will display the presence of voltage. An audible beep increases from
intermittent to continuous as intensity of field (EF) increases.
AC Voltage Detection Range:
24VAC to 600VAC (50-60Hz)
