±450 nA (±45 V) or ±1.5 µA (±150 V) into 100 MΩ load. Other ranges available on request.
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.
activated 10 % below maximum current.
ten-turn control, switch selected range max. 1 µA / 100 nA.
ten-turn control, max. 100 nA.
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.
sensitivity 100 nA / V, Rin > 100 kΩ, range ±10 V.
sensitivity 100 nA / V, Rout = 50 Ω, not isolated.
Vel / 10, Rout = 50 Ω, not isolated.
ELECTRODE RESISTANCE TEST:
obtained by application of square current pulses, ±10 nA from built-in pulse generator.
115 / 230 V AC, 45 – 60 W.
