SAFETY INSTRUCTIONS AND SYMBOLS This manual contains up to three levels of safety instructions that must be observed in order to avoid personal injury and/or damage to equipment or other property. These are: DANGER Indicates a hazard that could result in death or serious bodily harm if the safety instruction is not observed.
SAFETY WARNINGS AND CLEANING INSTRUCTIONS DANGER Opening the cover of this instrument is likely to expose dangerous voltages. Disconnect the instrument from all voltage sources while it is being opened. WARNING Using this instrument in a manner not specified by the manufacturer may impair the protection provided by the instrument.
This gate may be used to meter interpolation. When combined with a preset remotely control the 439 or it may be used to inhibit scaler such as the 431, this instrument forms a the digitized output with the multichannel analyzer digital charge integrator.
Power Supply with a full complement of to the input of the 439, it may be necessary to leave modules in the Bin; however, this may not be true the cable shield ungrounded at the current source.
The gate circuit will permit normal not create a voltage of more than 10 mV on C. For operation of the 439 when the gate input is at +3 V instance, if each beam pulse contained 10 or greater.
4. OPERATING INSTRUCTIONS Note: The accuracy of the 439 is not affected as long 4.1. TEST-OPERATE SWITCH as the Bal and Trig adjustments are within ±4 The Test-Operate is a three-position switch which divisions of zero. controls the function of the instrument:...
Note: If a voltage and a resistor are used to form a current source, the voltage source should have a 7. Adjust the Bal potentiometer to zero the Bal/Trig value greater than 5 V. The accuracy of the 439 is Meter. 1000 ppm, which is better than the temperature and/or voltage coefficients of most high-value 8.
Bal/Trig Meter. positive current and the 10 Coulomb/pulse range for negative current. If a negative current is 7. Connect the digitized output of the 439 to a scaler measured on the 10 or 10 Coulomb/pulse range that has an internal time base.
Digital voltmeter should read 100 mV with 1.5% 22. Set the Coulomb/pulse switch to 10 tolerance. 23. Connect a 10-mA test current to the 439 input. 15. Adjust the variable current source until the digitized output rate reads 1000 Hz.
Digital voltmeter should read 100 mV with 1.5% tolerance. Notes: The analog portion of the 439 is now calibrated. 1. All voltages were measured from ground with a voltmeter having an input impedance of 10 M or 5.3. SUGGESTIONS FOR greater.
