Operation
CAUTION
Before and after hazardous voltage measurements, test the voltage function on a known
source such as line voltage to determine proper meter functioning.
AutoCheck
TM
mode (525s, 521s, 829s only)
This innovative AutoCheck
TM
feature automatically selects measurement function of DCV,
ACV or Resistance () based on the input via the test leads.
● With no input, the meter displays “Auto” when it is ready.
● With no voltage signal but a resistance below 60M is present, the meter displays the
resistance value. When below “Audible Threshold“ is present, the meter further gives a
continuity beep tone.
● When a signal above the threshold of 1.5V DC or 3V AC up to the rated 1000V is
present, the meter displays the voltage value in appropriate DC or AC, whichever larger
in peak magnitude.
