HOW TO ELIMINATE DETECTING
OVERLAPPING MAGNETIC FIELDS
THIS CONDITION OCCURS IF TWO OR MORE LARGE SOLENOIDS OR
RELAYS ARE CLOSE TOGETHER.
DEPENDING ON HOW YOU USE THE HIGH/LOW
SENSITIVITY RING, YOU WILL BE ABLE TO INCR!:ft,.SE OR DECREASE
THE 'MAG-PROBE'S' SENSITIVITY
IN THIS CASE, YOU WANT TO REDUCE THE SENSITIVITY
JUST ENOUGH TO DETECT ONLY ONE SOLENOID VALVE OR RELAY.
YOU MUST INSTALL THE HIGH/LOW SENSITIVITY RING
FOLLOW THE DIRECTIONS ON PAGE 2 FIGURES 3, 4 & 5
AC DEVICES
NO SPECIAL PRECAUTION IS NECESSARY. THE HIGH/LOW
SENSITIVITY RING MAY BE INSTALLED WITH THE WHITE
DOT IN EITHER DIRECTION.
DC DEVICES
EVEN IF YOU DON'T NEED THE HIGH/LOW RING TO DETECT
THE DC DEVICE, YOU MUST INSTALL IT IN ORDER TO
REDUCE THE 'MAG-PROSE'S' SENSITIVITY.
AFTER INSTALLING THE HIGH/LOW RING, TRY TO
DETECT THE LARGE DEVICE WITH THE POWER APPLIED.
(SEE 'TESTING DC POWERED DEVICES'. IT MAY BE
NECESSARY TO REVERSE THE HIGH/LOW RING.)
AC & DC DEVICES
SLIDE THE HIGH/LOW RING SLIGHTLY IN THE DIRECTION
OF THE 'MAG-PROBE'S' LED, TRY IT ON THE DEVICE
UNDER TEST, FIGURE 2, KEEP SLIDING THE HIGH/LOW
RING TOWARD THE 'MAG-PROBE'S' LED UNTIL THE 'MAG
PROBE'S' TIP ALMOST TOUCHES THE DEVICE UNDER TEST
BEFORE THE LED TURNS ON. NOW YOU'LL
DETECT ONLY THE DEVICE UNDER TEST. (IF YOU TEST
LARGE SOLENOIDS AND RELAYS A MAJORITY OF THE
TIME, USE A STANDARD 'MAG-PROBE' MODEL'S'.
ESTIMATING HIGH OR_ LOW VOLTAGES
STANDARD SIZED AND LARGER
SOLENOIDS AND RELAYS ONLY
(DON'T USE THE HIGH/LOW SENSITIVITY RING). WITH A LITTLE
PRACTICE YOU SHOULD BE ABLE TO DETERMINE IF A HIGH OR LOW
VOLTAGE CONDITION_ EXISTS. FOR EXAMPLE: AFTER TESTING A 12
VDC SOLENOID VALVESEVERAL TIMES, YOU NOTICE THATTHE
'MAG-PROBE' LIGHTS AT APPROXIMATELY THE SAME DISTANCE.
(TEST THE SAME POINT EACH TIME). THI$ IS NORMAL IF THE
VOLTAGE IS CONSTANT. HOWEVER, IF THE 'MAG-PROBE' LIGHTS AT
EITHER A CLOSER OR GREATER DISTANCE FROM THE DEVICE THAN
NORMAL, THEN A VOLTAGE CHANGE HAS OCCURRED. AN
INCREASE IN VOLTAGE INCREASES THE MAGNETIC FIELD. THUS, A
LOW VOLTAGE WOULD DECREASE THE MAGNETIC FIELD. OF
COURSE, THERE IS A CHANCE THAT A RESISTANCE CHANGE HAS
TAKEN PLACE WITHIN THE DEVICE UNDER TEST, BUT THE ODDS (BY
A LONG SHOl) FAVOR A VOLTAGE CHANGE.
TESTING FOR RESIDUAL MAGNETISM
IF YOU SUSPECT THAT RESIDUAL MAGNETISM IS CAUSING A
MALFUNCTION, INSTALL THE HIGH SENSITIVITY RING ON THE 'MAG
PROBE' PER INSTRUCTIONS FOR HIGH SENSITIVITY NEXT, TURN
OFF THE POWER TO THE DEVICE UNDER TEST. NOW FOLLOW THE
PROCEDURE FOR TESTING AC & DC DEVICES. FIG 2
IF THE LED TURNS ON, YOU'VE FOUND RESIDUAL A
MAGNETIC FIELD.
TO BE DOUBLE SURE, REVERSE THE RING AND TEST
AGAIN. (YOU MAY HAVE A SOUTH POLE.)
IF CONTROL SWITCHES ARE BEYOND ARMS LENGTH, TAPE THE
'MAG-PROSE'S' TIP TO THE DEVICE UNDER TEST, OBSERVE THE
LED AS YOU CYCLE THE MACHINE. (MASKING TAPE WORKS WELL)
IF THE DEVICE TO BE TESTED IS LOCATED IN AN ELECTRICALLY
HOT AREA, TAPE THE 'MAG-PROBE' TO A WOODEN DOWEL OR
OTHER NON-CONDUCTIVE MATERIAL. NOW YOU CAN INSERT THE
'MAG-PROBE' DEEP INSIDE EQUIPMENT WITHOUT DANGER OF
SHOCK. KEEP YOUR HANDS AND ARMS CLEAR OF EXPOSED WIRE.
BEFORE TROUBLE SHOOTING USING THE HIGH/LOW SENSITIVITY
RING, PRACTICE ADJUSTING YOUR 'MAG-PROBE' FOR MAXIMUM
SENSITIVITY TRY IT ON A SMALL PERMANENT MAGNET.
GOOD TROUBLE SHOOTING!
THE BLACK TUBE. LOCATED IN THE STORAGE BAG, SUPS OVER
THE RED CAP AND SHIELDS THE LED FROM BRIGHT SUNLIGHT OR
BRIGHT INDOOR LIGHTS.
