1.HOLIDAY DETECTOR FUNCTION

The Tinker & Rasor Models AP and AP/WHoliday Detectors are portable, all purpose
inspection instruments. They are adaptablefor use on both large and small diameter pipe as well as flat surfaceswhen such surfaces are coated with a high electrical resistant materialand the surface beneath the coating is electrically conductive. The ModelsAP and AP/W Holiday Detectors work equally well on damp surfaces; theyare especially desirable when humid conditions exist or when it has recentlyrained. 
 
 

2.UNPACKING & INSPECTION

A. Upon opening the carrying case, noticewhere the various components are located; 
     repack them inthe same manner when not in use. Then remove all components from the 
     carrying case. 

B. Inspection should be performed uponreceipt. If damage has occurred in shipment, file 
     a claim withthe carrier immediately. Check components (against packing slip) to besure 
     nothing is missing. 

C. If it is necessary to contact your supplieror Tinker & Rasor concerning damaged or 
     missing items,be sure to include all information such as serial number, purchase order
     number and invoicenumber. 
 
 

3.CHECK-OUT INSTRUCTIONS

A. Assure that Holiday Detector "ON/OFF"switch is in the "OFF" position. 

B. Using the Battery Tester, insert testplug (on Battery Tester) into Holiday Detector "charge 
     plug" receptacle.Observe LED light , if "ON" battery has sufficient charge to operate the 
     detector. Thebattery tester is to be used only to test battery in case holiday detectordoes
     not operate properly.It is not designed to test the true condition nor the amount of charge 
     left in the battery. 
 

FOR MODEL AP HOLIDAY DETECTOR (ONLY)

A. Turn output voltage selection switch(on Detector) to desired voltage. (Voltages are listed 
     on the insideand outside of Detector back cover). 

B. Insert leather belt into slide loopson back of Detector if belt mounted method is to be 
     used. 

C. Uncoil high voltage cable and plug thelong connector (3" collar) into one end of adapter 
     and screw wandhandle onto other end of adapter; plug the short connector (1-1/2" collar) 
     into the Detectorhigh voltage port. 

D. Assemble the desired electrode to thewand assembly and apply to the pipe, tank, or 
     other structureto be inspected. An inspection electrode should always make intimate 
     contact withthe surface to be inspected. 

E. Turn "ON/OFF" switch to "ON" position.(Note: When the switch is "ON", a buzzing should 
     may be heardcoming from the Detector). 
 
 

FOR MODEL AP/WHOLIDAY DETECTOR (ONLY)

A. Turn output voltage selection switch(on Detector) to desired voltage. Voltages are listed 
     on the individualpowerpak in ascending order, left to right. 

B. Insert leather belt into slide loopson back of Detector if belt mounted method is used. 

C. Uncoil ground wire and plug connectorend into Detector port marked "ground". (The 
     ground wire willtrail on bare earth). 

D. Attach wand to threaded, male end ofpowerpak. Insert powerpak cable (male connector)
     into female connectorof powerpak. Insert other end of powerpak cable into
     "HighVoltage"port on Detector.

Note: Neverturn the AP/W on without plugging in the "HIGH VOLTAGE" cable or unplug
the cable whilethe unit is in the on position! Doing so will damage internal components.

E. Assemble the desired electrode to thewand assembly and apply to the pipe, tank, or other
     structure tobe inspected. An inspection electrode should always make intimate contact 
     with the surfaceto be inspected. 

F. Turn "ON/OFF" switch on "ON" position.(Note: When the switch is "ON", a buzzing sound
     may be heardcoming from the Detector). 

G. The AP/W is now ready to operate. 
 
 

4.OPERATING METHODS

A. Grounding

     1. A good groundsystem will always give the best and most reliable inspection. 
        The structure to be inspected must be grounded to earth at some point. 

     2. If individualjoints of pipe are to be inspected which are not electrically connected, 
        each joint must be grounded. 
 

B. Inspection Speed

     Speed of the electrodetravel over the inspection surface should be 
     moderate. Movingthe electrode at an excessive speed can result in a faulty inspection. 
 

C. Operating Checks

     1. Occasionalchecks of the Detector can be made if no holidays are being found. Move 
         the inspection electrode to the coating's edge (where the bare conductivesurface is); 
         note that Spark and signal should both occur. 

     2. If the signaldoes not sound when the spark jumps, the "ground return" resistance is 
         exceptionally high. (Example: very dry soil or very large diameter pipe).To improve 
         the "ground" make a direct connection between the structure under inspectionand the 
         Detector's ground wire. 
 
 

5.ABOUT YOUR HOLIDAY DETECTOR

A. Sensitivity Switch

     The sensitivityof the Holiday Detector may be adjusted by turning the 4-position switch; 
     access the switchwith a screwdriver through the porthole located on the back panel in the 
     belt recess.(See paragraph 6C). 
 

B. Output Voltages

     Output voltagesare measured direct-connected, "open-circuit" using Tinker & Rasor 
     Model "PRM" PeakReading Voltmeter calibrated to the Jennings Model J- 1005 
     Voltmeter 0 to100 kilovolts. 

CAUTION: Beforedisassembly of components, turn the "ON/OFF" switch to "OFF" position.
 
 

6.INSTRUMENT SERVICING

A. Cleaning

     Keep instrumentclean and dry. Clean instrument case with soft cloth dampened with 
     kerosene, thenwipe dry. Do not use solvents: (lacquer thinner, Methyl-Ethyl-Ketone, etc.) 
 

B. Voltage Output Checks

     1. Low outputvoltage: 

         a. Check position of voltage selector switch. 
         b. Check battery condition using Battery Tester. (See later comments onBattery). 
         c. Check for "parted" conductor in wand and ground wire(s). 
 

     2. No Output Voltage: 

         a. Check battery condition using Battery Tester. (See later comments onBattery). 
         b. Check fuse located on printed circuit board inside instrument. If fuseis blown, look 
              for shorted wire in primary circuit. Replace fuse with 2.0 amp fuse, type3AG. 
         c. Check battery leads and the power switch for open circuit. Proper inputcurrent is 
             .7 to .9 amperes. 
 

C. False Signal Indication Check

     1. Adjust 4-positionrotary signal sensitivity switch through porthole provided on back panel
         in the belt recess.

         a. Electrical "load" conditions vary greatly through pipe sizes, coatingthickness and 
             climatic conditions. The counter-clockwise position is the most "signalsensitive". 
             Coated concrete pipes would use this position. In other cases, it is bestto start out 
             using position 
 

     2. or the nextposition in

         a. clockwise direction.
         b. check for "parted" conductor in wand and ground wire. 
 

D. No signal with Spark Discharge 

     1. Check positionof signal sensitivity switch. 
     2. Read item3 --C under "Instrument Servicing".
     3. Refer to paragraphon "Operating Checks". 
 
 

7.BATTERY CHARGING - CAUTION

Place Holiday Detector "ON/OFF" Switchin "OFF" position while charging battery. 

A. Use only the Battery Charger provided(Part #031-005). 

B. Recharge battery in the instrument.Ventilation holes in front and back of instrument case 
     should be keptopen. 

C. Plug charger into polarized receptacleof instrument. 

Note: Battery cannot be testedor charged if instrument power switch is in the "ON" position.

D. Plug A.C. power cord into any 120 volt60 Hz outlet.. 

E. Charge battery for 14 hours. 

F. Charge battery at temperatures above45 degrees for best results. 

G. If charger pilot light "out": (indicatesCharger is not operating). 

     1. Check positionof power switch. 
     2. Check for"shorted" battery cell(s). 
 

H. Disconnect charger from battery andA.C. outlet when not in use. 
 
 

8.BATTERY MAINTENANCE

A. When instrument fails to operate innormal manner, battery maybe fully discharged. 
     Recharging beforethis happens can extend the useful life of the battery considerably. 

B. Store at normal room temperature whennot in use. 

C. If battery has not been used for sixmonth or more, discharge completely and recharge for 
     14 hours minimum. 

Note: If Holiday Detector failsto operate in normal manor, the first step is to test the battery condition.
