ZEROING PRESSURE SCALES – When there is no pressure applied to either port, the
display should read “0.” It may be necessary to zero the pressure scales to remove any
errors due to ambient conditions. This is done by pressing the key until the
zeroing instructions are displayed, then pressing simultaneously to begin the
process. The “ZEROING…” message will flash while the scale is being zeroed.
When the zeroing instructions are displayed again, the process is complete.
NOTE: Each sensor needs to be zeroed separately.
LOW BATTERY – When the battery life reaches 10 percent, the LOW BATTERY message
box will be displayed.
NOTE: A battery eliminator receptacle is provided so that the unit can be powered by the
optional 9 VDC Battery Eliminator, enabling continuous operation.
NOTE: The unit is shipped with a Red Battery Lock-Out plug installed into the line power
receptacle as shown below. Its purpose is to prevent the unit from accidentally being
turned on during handling and transport, subsequently depleting the battery. This plug
must be removed before any use!
