Almost empty (less than one day)
[1] When critically low, a “Replace batteries” pop-up message appears
15 seconds before the Meter shuts down.
The Meter will display a “Batteries low” message whenever the battery
level will not support a selected function.
Input Alert™ Feature
If a test lead is plugged into the mor A terminal, but the rotary switch is
not set to the correct current position, the Meter makes a chirping sound
and displays “Leads connected incorrectly”.
W Caution
To avoid circuit damage and possibly blowing the Meter’s
current fuse, do not place the probes across (in parallel
with) a powered circuit when a lead is plugged into a
current terminal. This causes a short circuit because the
resistance through the Meter's current terminals is very
low.
Maintenance
XWWarning
To avoid electrical shock or personal injury, repairs or
servicing not covered in this manual should be performed
only by qualified personnel as described in the
287/289 Service Information.
General Maintenance
For general maintenance refer to the 287/289 Users Manual on the
accompanying CD.
Testing the Fuses
With the Meter in the S function, insert a test lead into the W
jack and place the probe tip on the other end of the test lead against the
metal of the current input jack. Disregard the “Leads Connected
Incorrectly” message, if it should appear. The resistance value should be
between 0.00 and 0.50 Ω for the A jack and 10.00 ±0.05 kΩ for the m
jack.
