Page 7: Set-Up Procedures
Set-Up Procedures Power Requirements Recorders are shipped ready to operate on a nominal AC voltage of 120 VAC, 60 Hz or 240 VAC, 60 Hz as per country specifications. Conversion can be made to an alternate voltage moving a slide switch (inside the instrument) to the proper position and installing the correct fuses (0.15a). -
Page 8: Grounding
ROCEDURES Grounding For best performance, the green (or green and yellow) ground wire in the power cord for the recorder and the signal source should share a common "water pipe" ground. The green Caution (green and yellow) wire in the power cord, is connected to the ground (chassis) and to the ground pin of the AC power DO NOT connect the POWER connector, but not to the signal input. -

ROCEDURES Manual Paper Advance/Rewind The paper may be manually positioned as desired at any time using the advance/rewind knob on the right side of the recorder. -
Page 14: General Theory
General Theory General Theory The DC input signal to the recorder is first filtered, then amplified by the preamplifier to a level which is less susceptible to noise and interference. This conditioned signal is then applied to the servo amplifier which continuously compares it to the feedback signal developed by the servo potentiometer. -
Page 16: Calibration Procedure
Calibration Calibration This recorder is designed to be simple, reliable, as well as easy to maintain and repair. Therefore, the procedure presented here will be as simple, clear and brief as possible. For special problems, we recommend that you contact your local representative or the factory service department. -

ALIBRATION C. Position the chassis and bottom cover for assess to adjustments (See Figure 5.) Do not allow any circuitry to short to each other or to the chassis. Connect power cord to suitable power source and turn recorder ON. D. - Page 18 ALIBRATION I. Reset the pen to the setting in step "G" (50%) with the I (R-6) pot on the Control Panel PCB. J. Set the INPUT RANGE switch to 5. K. Repeat steps "D" through "J" until minimum (±0.5% maximum) pen movement is achieved. L.

Special Features Special Features Remote Chart On/Off Provides the ability to turn the chart on and off from a remote location when a contact closure is made or broken between "CHART OSC OUT" and "CHART PROG" of TB1 on the bottom panel. - Page 21 PECIAL EATURES EXAMPLE: The selector switch is set at 30 CM/MIN and the external frequency is changed to 137.5 Hz (a 10% increase). The chart will now run at 33 Note: CM/MIN. Changes of external frequency The recommended maximum chart speed for start/stop affect all selector speeds by the operation is 30 CM/MIN.
