Display Hold; Taking Measurements - Fluke 771 Instruction Sheet

Display HOLD

To prevent electric shock, when Display HOLD is
activated, the display will not change when a
different current is applied.
Pressing  activates Display Hold mode. The display shows
 and the Meter freezes the display. To exit and return to
normal operation, press  a second time.
Auto Off
The Meter automatically turns off after 15 minutes of inactivity. To
disable the Auto Off feature, hold down  while turning on the
Meter. If the Meter has automatically shut down, restart it by
pushing  ("WAKE UP").

Taking Measurements

The Clamp Meter is not for use on non-insulated
conductors.
Measurements can be taken with the clamp in the docked
position, or remotely via the 1 m cable. For accurate
measurements:
Always zero the Meter prior to taking measurements.
•
Zero the Meter as close to the measurement source as
•
possible.
Make sure the clamp is free of contamination.
•
To reduce magnetic influences, zero the Meter in the
same position or jaw direction that is used for the
measurements.
