(1) If you think the WGR has been moved or knocked out of place, contact a qualified service
technician to re-calibrate the WGR.
(2) If the WGR is installed on equipment that is prone to vibration, the WGR may have slipped out of
place. Contact a qualified service technician to re-secure and re-calibrate the WGR.
ii) There WGR is having difficulty reading the gauge due to obstruction or vibration
(1) If the gauge is installed outdoors, condensate buildup inside the gauge itself may impact the
WGR from obtaining a good reading. If possible, install a liquid-filled gauge and have the WGR
re-installed and re-calibrated.
(2) If the gauge has multiple needles, the WGR may have an issue identifying which needle to read.
Try to install a gauge with only one needle. This issue should be raised by the service technician
during installation.
(3) If the gauge only has one needle, but there is nothing to distinguish one end of the needle from
the other, the WGR may have problems obtaining a reading. If possible, install a gauge that has a
different type of pointer. This issue should be raised by the service technician during installation.
(4) If the equipment that the gauge is monitoring causes the gauge needle to vibrate very rapidly
(such as some compressors), then the WGR may have difficulty capturing a clean reading from
the gauge. In this case, please replace the gauge with a dampened or liquid-filled gauge to slow
the motion of the needle. Then have the WGR re-installed and re-calibrated by a qualified
service technician.
iii) The pointer of the gauge has broken.
In some cases, gauges that are installed on equipment that are prone to vibration can break needles.
If you suspect this is the problem, contact a qualified service technician. If you remove the WGR
yourself to determine if this is the issue, you will still need to have the WGR re-calibrated.
iv) The wireless connectivity of the WGR to the server is weak.
In some cases, the wireless signal strength of a WGR to the server is affected by facility changes.
Weak connectivity from the WGR to the server will cause an error message. The ERROR message
should also be associated with a missing ANTENNA icon in the lower right hand corner of the LCD.
Contact a qualified service technician if this problem occurs.
If you have additional problems, please contact us. See Section 10.0, Support, for contact information.
