Frequency (Pro Lcd Only); Self Test; Ncv Test (Pro Lcd Only); Hold Function (Pro Lcd Only) - Nieaf-Smitt EazyVolt Pro Mode D'emploi

7.13 Frequency test (Pro LCD only)
• Switch into frequency measurement by short pressing 4 times
the button or repeat short pressing until Hz symbol is
shown on LCD. Fr and Hz symbol should be on LCD. Connect
both test probes to the AC voltage under test. Frequency from
1 Hz to 800 Hz can be shown on LCD
Frequency measurement is possible for voltages >10 VAC
• The level of voltage will be shown only on the bar graph
7.14

Self test

• LEDs up to 50 V (Pro LED), all LCD segments and vibration
motor (Pro LCD), torch light, ELV indication and buzzer are
turned on for a second after battery replacement or selftest

• White Backlight is on all the time while tester is turned on
• Backlight will be green when voltage <50 VAC or <120 VDC
• Backlight will be red when voltages >50 VAC or >120 VDC and
for single pole detection
7.18

Battery Replacement
