Error Messages and Testing the Cables and Transducers
AwayoftestingthatthecablesandtransducersareworkingistoconnectthemalluptothePT878GCandputthetransducertoyourear.Listen
out for a frequent buzzing sound. If you do not hear this there is a problem with either the cables or transducers.
Make sure the transducers are spaced properly.
Error messages - error code messages are displayed when the PT878 is displaying measurements. For meanings of error messages and a full list
ofsolutions,pleaserefertotheDiagnosisandTroubleshootingsectionoftheGEPanametricsOperationandInstallationGuide.

using dampening material please refer to the installing dampening material section.
1.Theclampingxtureisinstalledintwohalves.Thersthalfofthextureisinstalledwiththefourrods,needstobe
positioned on the horizontal plane on the pipe at the 3 o’clock position.
Installing the Clamping Fixture
3.Thefournutsshouldnowbeinstalledontotherodswiththeconvexsideofthenutfacingthexture.Hand
tighten the nuts.
2.Thesecondhalfofthextureshouldbepositionedoverthethreadedrodsinthe9o’clockposition.
2.Therstmountingblockshouldbesetataconvenientnumber
onthescalesuchas1inor1cm.Installthersttransducerinthe
mounting block with the BNC connector pointing away from the
center of the V block xure. Tighten the thumbscrew onto the
slider until the transducer is tight against the pipe surface.
1. Apply a thin line of couplant along the entire length of each
transducer face.
3. Set the second mounting block to the calculated spacing plus
theinitialscalenumberselectedfortherstmountingblock.
4. Install the second transducer in the same way.
Note: Eachhalfofthexturehasameasuringscale.Ensurethatthescalesareonthesamesideofthexture
with zero at the same origin.
Installing the Transducers
Installing the Dampening Material
1.Oncetheclampshavebeeninstalled,useamarkerpentomarktheinsideedgesofthebracketsonthepipe.
2.Removetheclampingxturesandtransducersfromthepipe.
3. Thoroughly dry the pipe using a towel or rag.
4.Cutanequallengthtothecircumference,ofdampeningmaterialandpeeloffthepaperbacker.
5. Wrap around the pipe following the lines already marked on the pipe which represent the inside edge of the clamping
xture.
6.Theclampingxturenowneedstobereinstalledandthetransducers
mounted ensuring the spacing is set correctly.
7.Usingamarkerpen,drawaroundthetransduceroutline.
8.Onceagainremovethetransducersandclampingxture.Useaknife
to cut out the transducer shape and peel the dampening material from
the pipe.
9. Clean the cut out area of the pipe to remove any excess residue.
10.Reinstalltheclampingxtureandtransducers.
11.Cutanotherlengthofdampeningmaterial,equaltothecircumference.
Cutthisintotwopieces,each4.5inwide.
12.Wraponestriponeachsideoftheclampingxture.
