Digital circuit tester

SPECIFICATION
• Digital display to read the accurate voltage value
• Available for 6, 12, 24V 48V DC system
• LED indication for power (red) and ground (green)
• Stainless steel testing probe
• Voltage measurement from 4 - 60V
• Spring cable, which is able to extend to 3 meters
• Small testing current: <10mA

VOLTAGE MEASUREMENT
1.Red clip connect with positive (+) polarity,
and black clip connect with negative (-) polarity.
2.When the tester probe connects with positive voltage,
the nixie light will display the voltage. If the voltage is less than 0.3VDC,
the nixie light will still show “00.0”. If the voltage is greater than 62VDC,
the nixie light will display “Err”.
