Technical Data

HEADSTAGES:
Size (approx.): Standard 65x25x25 mm, holding bar diameter 8 mm, length 150 mm, mounting plate or dovetail on request,
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.

POWER REQUIREMENTS:
115 / 230 V AC, 45 – 60 W.
