Measurement Dial
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 Resolution: 0.1mV
Accuracy: ±(1.5% + 10) 50Hz to 60Hz
±(2.0% + 10) 60Hz to 400Hz
Unspecified at 400Hz and greater
Minimum Input Voltage Range: >20 digits
Low Pass Filter: >1 kHz
Crest Factor: ≤ 3
Audio/Visual Hi-V Indicator: >30VAC/VDC
Input Impedance: 5MΩ
Overload Protection: 1000VDC or 750VAC rms
Volts DC (VDC)
Select VDC and measure DC voltages on circuit boards on more
advanced HVACR systems and logic control boards. In VDC/ADC dial
position, VDC is shown on lower display. Press SELECT button to show ADC
on the top display at the same time.
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)
