****** Page 4 ****** INTRODUCTION Models PAV2X, PAV2X-T, PAV3X, PAV3X.T, PAV4X, PAV4XeT are exe panded scale single phase AC Voltage Recorders, i.e., their scales do not start at zero. Models PAV86Ø and PAV86m-T are three range single phase AC Voltage Recorders with scales that start from zero. Range selection on all models is done by moving the range selector switch on recorder panel. 6 PAV2X, PAV2X.T PAV3X, PAV3X.T PAV4X, PAV4X-T 50 Hz ONLY PAVBSOO, SPECIFICATIONS Wage 951w, Volts am 5m Volts 165-245; Volts CYErt Papr 835X3A or 835X3A$* 835YQA or 8.35X3A+ 840X2 or 840X2$* 8.30AVÜ.a• • ft. chart supplied; -6 is ft. chart foe take-cp mo±ls only.

If adjustments are necessary proceed as follows: a) Remove top cover—pull bottom ledge of frame toward you and lift. See fig. 3 or 4. b) With strip chart roll not In recorder, locate star wheel. See fig. c) Apply finger to star wheel and turn until pointer lines up with zero mark at the extreme right of scale.

Move chart drive switch to “OFF” position exposing the word “OFF.” See fig. 1. 2. Remove top cover. See fig. 4. 3. Unroll about nine (9) inches of chart paper. 4. With printed side up, slip leading edge of paper under the glass and out, through slot in front as shown in fig. 7. 5. Make sure the holes on both sides of the chart paper engage the sprockets of both capstan wheels. 6. Line up time arrow (see fig. 8) with any line on the left of the chart paper. 7.

Move chart drive switch to “OFF” posi- tion exposing the word “OFF.” See fig. 1. 2. Remove top cover. See fig. 3. 3. To insert or remove chart paper, place recorder in horizontal position and press the release button in the direction shown in fig. 10. Raise recorder mechanism to a vertical position until it locks. Remove feed shaft @ (see fig. 9) and place chart roll on spindle. Remove tape on roll and retain tape for securing chart on take-up spindle O. Unroll about 12″ to 15″ and route paper over top edge of scale plate @ underneath glass, over the sprocket wheels, to the rear and over the Idle roller O up to the cardboard bobbin mounted on take-up spindle O. Secure edge of chart to bobbin with tape. Make sure the sprocket holes in the paper engage the sprocket wheels. Be 10 sure that feed control is tight and in the right position. The word “ON” must be visible. Press in the idle roller extension O to allow the recording mechanism to move back down into case and lock into position. Replace cover by positioning the “U” bend onto the plastic projections and snap front down. Make sure chart paper Is not binding with the cover in place. For “non- take-up” recording, route chart through bottom slot as shown In fig. 9. 4. To remove chart from take-up spindle O, move the latches away from the take-up spindle. Turn knurled knob on spindle @ until the slot in the take-up drive pulley at the opposite end of the spindle is lined up with the slot In the side frame of the recorder. Slide the spindle and chart up and out of the slots in the side frames of the recorder. Remove tape from chart and bobbin. 5. To unload chart paper from recorder turn chart drive switch off, exposing the word “OFF”. See fig. 1. Follow 4 above. Remove chart from feed shaft @ and pull paper thru recorder. SELECTINO CHART SPEED ON TAKE-UP MODELS 1. To select chart speed, energize recorder with proper line voltage and frequency. Raise recorder to vertical posltlon (see loading and unloading chart paper on take-up models). Move chart drive switch to “ON” position exposing the word “ON”. Make sure switch clicks into detent (see fig. 11). Set all three speeds to “OFF” position and tighten (see fig. 9). Move desired speed knob (1, 12 or 24) to “ON” position. Tighten while keeping pressure on gear mechanism. 2. Press in the Idle roller extension O to allow the recording mechanism to move back down into the case and tock into posl• tion. Replace cover by positioning the “U” bend onto the projec- tions above the chart well opening. Make sure chart paper is not binding with the cover in place. For “non-take-up” recording route chart through bottom slot as shown in figure 9. HOW TO USE AS A RECORDER 1. Chart drive switch must be In “OFF” position (exposing the word “OFF”). See fig. 1. 2. Remove top cover. Adjust zero setting. (See Zero Adjusting). 3. Load chart paper. See fig. 7 or 9. Replace cover by positioning “U” bend onto the metal projections of chart well (non-take-up) and onto molded plastic projections for take-up recorder and then snap front down. Make sure paper is not binding with cover in place. 4. Connect meter line cord (two prong) to recorder and to voltage source to be measured. Use adaptor if necessary. 11
****** Page 7 ****** 5. Move range switch to range that allows pointer to be nearest to F.S. deflection. 6. Plug power line cord into recorder line receptacle and connect to proper line voltage and frequency. 7. Push chart drive switch to “ON” position (exposing the word “ON”). See fig. 11. Make sure switch clicks into detent position which tocks it into place. 8. Mark time of start on chart paper. See fig. 8. 9. Secure recorder in a horizontal or vertical position. READING STRIP CHARTS In some cases strip charts have than one scale. æad on the scale that corresponds to the range you are using. If the particular range you are using does not appear on the chart, use a scale with numbers that you can easily convert to the range you need. HOW TO USE AS AN INDICATING METER Follow steps 1, 2, 4, 5 and 6 of “I-bw To Use As A Recorder.” chart paper removed, read directly on scale plate. SERVICE With Serial number is die stamped in lower right hand comer of the scale plate.
