INSTRUMENT DESCRIPTION The following controls are available for both the Hold and Eject channels. POWER ON/OFF–Instrument power switch/external 5V DC. To maximize battery life, turn the power OFF when the channel is not in use. CURRENT LEVEL–This control varies the current amplitude as indicated on the ammeter. To prevent accidental current flow via the output terminals, place the OUTPUT switch in the PRESET position while adjusting current amplitude. CURRENT RANGE–Selects either 100 or 1000nA current range MODE SELECT–MANUAL operation allows you to apply a DC current when the OUTPUT switch is changed from PRESET to ENABLE. AUTO operation requires you to apply a +5V command potential to initiate the flow of current. OUTPUT POLARITY–NORMAL indicates that the red output connector is positive with respect to the black connector. INVERT reverses connector polarity. AUTO INPUT–If the MODE SELECT switch is in the AUTO position, the AUTO INPUT connector controls current activation. Five volts positive with respect to the outer connector shell maintains the current for as long as this voltage is applied. The CURRENT LEVEL control continues to dictate the actual current amplitude. OUTPUT–In the PRESET position, the red and black current output terminals are disconnected from the current generating circuit. ENABLE connects the output terminals to the current source. If the OUTPUT switch is in the PRESET mode, current cannot flow out of the instrument in either MANUAL or AUTO operating modes. CHAS GND–This green binding post is connected to the chassis or metallic enclosure of the instrument. It should normally be connected to the ground point of your recording system. FULL MANUAL - HERE
