AquaLab 12 TROUBLESHOOTING
SOLUTIONS:
1. Check to make sure your power cord is securely attached to the
back of the instrument and it is plugged into the power outlet.
2. A power surge may have caused a fuse to blow. To change the
fuses, follow instructions a through d.
(a) Unplug the power cord.
(b) Locate the panel where the power cord plugs in. The fuse
box is on the right side of that panel. Press in on the
release tab and pull the fuse-holder out. Pull the broken
fuse(s) out and replace with a 1.25 Amp 250 V fuse.
Caution: Do not use any other kind of fuse or you
risk damaging your instrument as well as voiding
your warranty.
(c) Replace the fuse-holder and push it into the fuse-well until
the release tab snaps in place.
(d) Connect the power cord and turn your instrument on. If
the fuse blows again, a failed component may be causing
the problem. Contact Decagon to make arrangements for
repairs.
2. PROBLEM:
Readings are slow or inconsistent.
SOLUTIONS:
1. The sample chamber may be dirty. Refer to Section 6 for di-
rections on cleaning the sample chamber.
2. The temperature difference between the sample and the block
chamber may be too great. The sample needs to equilibrate
to instrument temperature before a fast, accurate reading can
be made. (Refer to Section 8, Samples Not at Room Temper-
ature.)
