Extending the Probe
To extend the probe, hold the handle in one hand while pulling on the
probe tip with the other hand. Do not hold the cable while extending the
probe as this prevents the probe from moving.
Retracting the Probe
To retract the probe, hold the handle in one hand while pushing on the
probe tip with the other hand. If you feel the probe antenna binding, pull
gently on the probe cable until the smallest antenna section is retracted.
Collapse the rest of the antenna by pressing the probe tip.
Articulating Probe (Models 8384A/8385A/8386A Only)
The articulating probe has the ability to bend at a 90° angle for those
hard to reach places. To bend the probe, loosen the knurled nut on the
joint, bend the probe, and tighten the nut. To straighten the probe,
loosen the nut, straighten the probe, and tighten the nut.
Changing the Real-Time Clock

Plus has an internal real-time clock that keeps track of the
time of day (the format is HH.MM where HH is the hour in 24-hour format
and MM is minutes) and the date. It is very important to set the time and
date correctly, otherwise date and time stamping of recorded data will not be
correct. This information has been set to Central Time at the factory before
shipping.

Plus beeps twice. You will have an opportunity to view and/or
change the hours, minutes, year, month, and day of month in sequence. Use
the up and down arrow keys (
