76J Pneumatic Fulscope Recorder INTRODUCTION RELATED DOCUMENTATION Additional documentation related to the use of the 440R can be found in the following documents. • IB-04F109 1401L - 1405L Model D Electrical-to-Motion Element (EME) for 76J, 120R. The 1400L Series EME units, are solid-state electro-mechanical units that convert electrical input signals to a mechanical movement compatible with the instrument linkage systems.
76J Pneumatic Fulscope Recorder INSTALLATION INSTALLATION UNPACKING Unpack and visually inspect the recorder. Normal shipment includes the following: • Box of 100 Charts. • Pen assortment for each recorder pen If the recorder has either the V-type pens or reservoir pens, the pen assortment consists of a 1/2 ounce bottle of ink with a dropper assembly for each pen color.
76J Pneumatic Fulscope Recorder INSTALLATION PROCESS CONNECTIONS CAUTION When installing thermal systems or volumetric type pressure systems never cut the flexible capillary tubing, and do not make bends smaller than a 3 " (76 mm) radius. 2.3.1 Thermal Systems Locate flexible connecting capillary tubing where it will not contact extremely hot or cold surfaces.
76J Pneumatic Fulscope Recorder INSTALLATION 2.3.2 Pressure Systems Open Element Type The open element type pressure system has a pressure connection at the bottom or back of the recorder case, Figure 2. Connect the process line to the 1/4" NPT port in the case fitting. If necessary, a pulsation damping unit can be installed in the liquid filled process line to reduce the effect of pulsations on the record.
76J Pneumatic Fulscope Recorder INSTALLATION Figure 5. Electrical Connections SETTING SPRING WOUND DUAL SPEED CHART DRIVE SWITCH Set the rotation period for the spring wound dual speed chart drive by setting the switch for either Hours or Days. Reference Table 3 and Figure 29 in the Parts List section. SETTING BATTERY OPERATED CHART DRIVE JUMPER Set the rotation period for the battery operated chart drive by placing the jumper as indicated in Figure 6.
76J Pneumatic Fulscope Recorder OPERATION OPERATION PREPARING RECORDER FOR OPERATION 1. Pull pen lifter forward to raise pen off chart, Figure 7. 2. Start chart drive as follows: a. Electric Chart Drive - Turn power on. b. Spring-Wound chart drive - Lift clamp in chart hub and remove chart. Wind clock using key supplied with recorder, then replace chart.
76J Pneumatic Fulscope Recorder OPERATION PEN IDENTIFICATION One-pen recorders are always supplied with a red pen. The measuring element is located on the upper right-hand side of the case. The location of the measuring elements and their associated pens is shown in Figure 8. The elements and pens are color coded for easy identification.
76J Pneumatic Fulscope Recorder MAINTENANCE MAINTENANCE CHANGING CHART 1. Pull pen lifter forward to raise pens off chart, Figure 9. 2. Lift clamp in chart hub and remove used chart. 3. Insert new chart on hub and engage edge of chart under chart retainer tabs. 4.
76J Pneumatic Fulscope Recorder MAINTENANCE Figure 9. Fiber-Tip Pen If the pen fails to touch the chart paper bend the pen arm slightly as described in paragraph 4.3.1. When the recorder is not in use, place the pen cap on the tip of the pen to protect and seal the tip from evaporation.
76J Pneumatic Fulscope Recorder MAINTENANCE For example, a typical thermal system has a range of 30 to 130°. First determine the span. Span = Upper Range Value – Lower Range Value Span = 130°F - 30°F = 100°F Next, determine the actual input value for 0, 100, and 50% of span for calibrating purposes. Input Value at Required % = (Required % x Span) + Lower Range Value Input Value at 0% =(0 x 100°F) + 30°F = 30°F...
76J Pneumatic Fulscope Recorder MAINTENANCE 4.4.2 Precalibration Alignment * NOTE: Precalibration alignment is required only if the recorder has been disassembled or if a major component has been replaced. If instrument has not been disturbed and requires only calibration, proceed to 4.4.3 Zero Adjustment.
76J Pneumatic Fulscope Recorder MAINTENANCE Figure 13. Adjusting Pen Arm Micrometer Screw 5. Rotate chart and place pen on a time line near 0%. Move pen up scale and observe if pen point follows the arc of the time line. If pen point tracks above the time line, slide the pen up the arm.

76J Pneumatic Fulscope Recorder MAINTENANCE 11. Observe linkage angles as shown in Figure 13. Continue changing pivot hole selection and Coarse zero adjustment until 90° angles appear with pen at midchart. Linkage is now square and aligned for calibration. 4.4.3 Zero Adjustment Refer to Figures 14, 15, and 16 for similar measuring element and locate related adjustments.
76J Pneumatic Fulscope Recorder MAINTENANCE 3. Repeat Zero, Span and Linearity adjustments for required accuracy. * NOTE: Changing hole selection from hole No. 1 to No. 6 changes linearity approximately 2%. If link appears to be too long or short, it may be necessary to move measuring element for additional correction as follows: With 50% input, loosen measuring element mounting screws and slide...
76J Pneumatic Fulscope Recorder MAINTENANCE 4.5.2 Thermal System 1. Turn off all electrical power to Fulscope. 2. Remove chart plate and connecting link. 3. Remove terminal block mounting screws and necessary wires to move terminal block for access to case opening. Refer to Figure 17. 4.
76J Pneumatic Fulscope Recorder MAINTENANCE Figure 18. Field Installation Calibration Tag Remove case fitting from access plate. * NOTE: In either of the following steps it may be necessary to release instrument mounting brackets to extend bottom of case forward for full access opening clearance.
