Changing the Batteries
NOTE :
For optimum performance, the
batteries should always be replaced with two
good quality AA alkaline batteries !!
Simply clip open the two side panels as shown
and remove the 4 screws, then flip the top
cover forward.
Remove the old batteries and discard
thoughtfully.
Insert the new batteries taking care of the
battery orientation – which is stamped on the
bottom of the battery enclosure.
After replacing with new batteries, if the Power ON/OFF button is depressed and the unit
appears not to turn
On
, do the following:
- Depress and release all three buttons at the same time. This is the same as
performing a hardware
Reset
. All settings will be restored and the unit will operate
normally. Be sure not to hold down the FUNCTION button too long as this causes
the PVD100 to power up with Factory Defaults. If this occurs, simply remove the
batteries while the unit is
On
, then replace the batteries. All previous settings
should be restored.
Please Note:
Installing the batteries backwards will not damage the
PVD100
.

Maintenance and Repair Procedure
There is no specific maintenance for the
PVD100
. As with any electronic device, care must
be taken to insure minimal exposure to moisture, dirt, or other contaminants. The unit has
waterproof connectors and an “O” ring seal between the two case halves, which prevents the
ingress of water and is rated to IP65.
There are no user serviceable parts inside the
PVD100
. If the unit does not function properly,
the unit must be returned to HyQuest Solutions for component repair.
The
PVD100
does not require any calibration or adjustments. The
PVD100
is self-
calibrating and will perform this operation whenever the unit is turned on and whenever
CALIBRT is selected via the menu, or whenever a start measurement command (‘
S
’) is
received through the serial communications interface.
