Illustration 38. Example Of Print Once (Prnt oncE) Printout.
Illustration 39. Example Of Print Continuous (Prnt cont) Printout. 3. The setting of the printer PRINT key can be shown on the display. To see the setting, hold down the PRINT key with Multitach II OFF, then press ON/OFF. When the display comes ON, it will show "Prnt oncE" or "Prnt cont" on it. To select the desired printing method, press PRINT and the setting will change. Leave the desired printing method on the display and exit by pressing any other key. You are now ready to print.
Illustration 40. Example Of Printout Of All Memories And Display (PRINT key held down for 3 seconds).4. Connect the printer and press print. If you are in the "Prnt oncE" mode, one set of readings will be printed and the printer will stop. If you are in the "Prnt cont" mode, the printer will print a set of readings every 10 seconds until stopped by pressing the PRINT key again.Checking the Operation of Multitach II
The following procedure can be used to make sure that Multitach II is operating properly and is accurate.An accurate frequency source is required. Either the 5P-9698 Calibrator (cancelled) or an 8T-5200 Signal Generator Counter Group can be used. The 9U-7506 Magnetic Adapter Cable can be used with either unit to connect to the RPM and HZ INPUT. Use the 8T-5197 Calibrator in the Signal Generator Group to connect to the Magnetic Adapter Cable.1. Turn ON the calibrator or signal generator counter. Read the HZ with Multitach II. The readings should agree + or - the accuracy in the specifications for both units. When measuring frequencies less than 1000 Hz, Multitach II will show 0.1 Hz resolution and will switch to the next full digit at 0.5.2. To check the RPM function, leave the calibrator or signal generator counter connected, and use this formula to determine what RPM should show on the Multitach II display for the input frequency. 3. To check the SET POINT operation, read any RPM value as described, then press SETPOINT. Install the 8T-5111 Rack Adapter Cable and the 1P-7446 Rack Cable in the SETPOINT INPUT being tested. With the clips on the rack cable not touching, OVERRUN should show on the display. When the clips are touching, LUG should show. Press the SAVE key and MEMORY should show on the display and be flashing. Touch the clips on the rack cable together rapidly and MEMORY should stop flashing. Change the frequency of the calibrator or signal generator. The RPM on the Multitach II display should remain constant. This checks the hold feature of SETPOINT. Press CLEAR and the Multitach II display should change to the new RPM value. Pressing MEM VALUE should bring up the last SETPOINT value measured.4. To check the 9U-5140 Photo Pickup operation, use a photo pickup installed in one RPM and HZ input and a tachometer generator reading the same rotating device. An
