5. OPERATIVE INSTRUCTIONS
5.1.
AC VOLTAGE DETECTION
With the selector switch set to “
V
” by taking the end of the clamp jaw near an AC source,
the red LED at the base of the clamp jaw will turn on (see Fig. 1 – part 2), which indicates
that voltage is present.
CAUTION
Phase detection is active only when the clamp selector switch is set to “
V
”
position
5.2.
DC VOLTAGE MEASUREMENT
CAUTION
The maximum DC input voltage is 1500V. When the display shows
“>
1500.0V
”, it means that the maximum value that clamp is capable of
measuring has been exceeded. Exceeding these limits could result in
electrical shocks to the user and damage to the instrument.
The CAT III 1000V marking on test leads guarantees the safe
measurement of voltage up to 1500V
