- Electrode connector: BNC connector,
- Ground connector: 2.4 mm connector.
- Electrode output: floating current source, output impedance >1012 Ω.
MAXIMUM CURRENT: ±450 nA (±45 V) or ±1.5 µA (±150 V) into 100 MΩ load. Other ranges available on request.
DISPLAY:
- current XXXX nA, voltage XXX.X V, REL XXXX MΩ,
- separate displays for each channel, displayed value is set by a three position toggle switch.
OVER LEDs: activated 10 % below maximum current.
EJECT: ten-turn control, switch selected range max. 1 µA / 100 nA.
RETAIN: ten-turn control, max. 100 nA.
CAPACITY COMPENSATION: range 0 30 pF, ten-turn control.
OUTPUT CURRENT POLARITY: selected by INVERTED / NORMAL toggle switch.
MODE of operation:
- set with toggle switches,
- EJECT / RETAIN / AUTO switch enables manual or TTL controlled operation,
- SET / OPERATE switch connects automatically electrode outputs to an internally grounded load, to make possible well defined presetting (SET position),
TTL INPUT (AUTO mode): LO = RETAIN, HI = EJECT, isolated, Rin > 5 kΩ.
ANALOG INPUT: sensitivity 100 nA / V, Rin > 100 kΩ, range ±10 V.
CURRENT MONITOR: sensitivity 100 nA / V, Rout = 50 Ω, not isolated.
VOLTAGE MONITOR: Vel / 10, Rout = 50 Ω, not isolated.
ELECTRODE RESISTANCE TEST: obtained by application of square current pulses, ±10 nA from built-in pulse generator.
