A, CONNECT THE TERMINALS MARKED C1 ANO Pl TOGETHER ANO CONNECT THEM TO THE ELECTROOE UNDER TEST

B, POSITION THE CZ PR08E ALONG A LINE WHICH MAXIMIZES THE DISTANCE FROM THE ELECTRODE UNDER TEST AND FROM OTHER BURIED METALS SUCH AS UTILITY PIPES POWER ANO SIGNAL CA8LES, fUEL TANKS, ETC, IN CHOOSING THE DIRECTION FOR PLACEMENT OF THE C2 PROBE, EXAMINE THE CONFIGURATION OF THE ELECTRODE SYSTEM, FOR THE FACILITY ANO DETERMINE THE LOCATION Of ALL SUCH BURIED IETALS, THEN LOCATE THE PR08E AS FAR AS POSSIBlE FROM THESE METALS AS ILLUSTRATED IN FIG, l IFOR LONG SYSTEMS SUCH AS ALS, THE CZ PROBE LINE SHOULD BE RUN 90 DEGREES TO ALSI KEEP C2 & PZ LEADS SEPARATED AS FAR AS

POSSIBLE,

C, POSITION THE CZ PROBE AT DISTANCES AS SHOWN IN FIG, J. RECORD THE METER READINGS FOR EACH C2 & PZ PROBE POSITION, (NOTE THAT THE P2 POSITIONS ARE 62� OF THE C2 POSITIONS>, IT MAY NOT BE NECESSARY TO PLOT THE FULL soo·. PLOT ENOUGH

POINTS TO ACCURATELY DETERMINE WHERE CURVE LEVELS OFF,

D, NEXT, PLOT ON A GRAPH AS MANY RECORDED RESISTANCE READINGS VERSUS THE CORRESPONDING CZ PROBE POSITIONS AS NECESSARY

TO DETERMINE WHERE CURVE LEVELS OFF. !FIG, 31
