Inserting Getting Started the Batteries Storage. The SR100 is supplied with the Remove battery covers as shown. Then, Traverse Unit (bottom) connected to the insert one 3V Lithium 2450 in to the Control Control Unit (top). Before use, separate the Unit and three 3V Lithium 2450s in to the Traverse Unit from the Control Unit. Traverse Unit as shown. Note: To prevent damage to the stylus, store the SR100 with the units connected. Then replace the battery covers. After the batteries have been changed, there will be a short delay when the SR100 is turned on. The SR100 can be operated in two modes: Remote or Connected. Remote: Position the Control Unit within 40" (1 meter) of the Traverse Unit. Data is passed between the two units over the IrDA link. Note: Alignment between the Traverse Unit and Control Turning On the SR100 When the Control Unit is not used for five minutes or more, it enters power save mode, turning the display off. Press any button to reactivate. Unit separation μmμin +- must be maintained during the measurement process. Connected: In connected mode, Ra Rz Rv Rp Rt the Control Unit is connected to the Traverse Unit before the measure- ment is made, as shown. To connect the Control Unit to the Traverse Unit, insert the Control Unit as shown and The Traverse Unit switches off com- pletely after five minutes of inactivity.

Low Battery Indicators Set Up Procedure A new SR100 is fully set up out of the box. However, if the pick-up is changed or another alteration is made, field setup may be required using the following procedure: Press the On button on the Traverse Unit. Position the traverse unit on the calibration standard in the correct orientation. First, press both selector buttons simultaneously and then press the right hand start button while still pressing both selector buttons. The display will go through the following sequence over a 50 second period. The control unit must remain pointed at the traverse unit during this entire cycle. Five values are stored and can be viewed by toggling the Selector button as follows: 1: Gain pot setting 2: Rz value (21.5 ±10%) 3: Speed pot setting 4: Rp value (Profile period signal (68 ±2%) 5: Can be ignored for this procedure Note: If a setup error occurs, the procedure terminates and an E code is transmitted and displayed in the Control Unit (see E codes). Calibrating the Gage Position the Traverse Unit to measure the Cali- μmμin +- μmμin +- bration Standard included with the SR100 (DO NOT use other standards). Press Mode Se- lect (on the Control Unit) until is indicated on Mode status. Ra Rz Rv Rp Rt Ra Rz Rv Rp Rt Press the Start button on the Control Unit to ini- tiate the gage calibration procedure. The result will be display the Control Unit. The Ra value should be 5.81μm and the Rz value 21.5μm. If there is an error, an E code is displayed (see E Codes). Measuring Operation of the Control Unit is identical in either the Connected or Remote mode. Position the Traverse Unit on the surface to be meas- ured, then press Select on the Control Unit to select the parameter to be displayed upon completion of the measurement. Select either English or metric units with the Mode button. If in remote mode, be sure to maintain line of sight of the infrared transceiv- ers during the measurement. Press either Start button to begin the measure- ment. The “measure- ment in progress” display is shown. The measured parameter is displayed as shown. If there is an error, the appropriate E code is displayed (see E Codes). All parameters (not just the selected param- eter) are transmitted to the Control Unit at the same time and temporarily stored. The stored results may then be stepped through using the select buttons. μin +- Control Unit Traverse Unit μmμin +- Ra Rz Rv Rp Rt μmμin +- μmμin +- Ra Rz Rv Rp Rt Ra Rz Rv Rp Rt μmμin +- Ra Rz Rv Rp Rt Specifications Traverse length: 0.2" (5mm) Measurement length: 0.16" (4mm) Traverse speed: 0.08in/s (2mm/s) Gauge range: 8000μin (200μm) Gauge resolution: 2μin (0.05μm) Display resolution: Ra. 0.4μin (0.01μm) Display resolution: 1μin (0.1μm) for Rz, Rt, Rp, Rv Cut off: 0.03" (0.8mm) ±15% Uncertainty: 4μin (0.1μm) or 5% of result, to 95% confidence level Results range: Ra. 1600μin (40μm) (See ISO 4288-1996) Results range: Rz, Rt, Rp, Rv. 8000μin (199.9μm) (See ISO 4288-1996) Stylus: Diamond.
