6-1
Operating voltage 110-120 V / 220-230 V / 240 V, 50/60 Hz
built-in battery 12 V.
External battery 12 V can be connected to terminals (9) on front
panel. (battery cable AA 3 red, Ident. No. 460-439 and AA 3 black,
Ident. No. 460-458 available as accessories).
Output voltage Stepless controllable with switch (2) 0-5 kV and switch (3) 0-25 kV.
Independent of load up to 1 mA output current.
Output current Short-circuit current approx. 3 mA; continuous current 1 mA at
25 kV.
Voltage indication Voltage measurements are performed directly at the output via a
precision measuring resistor (1%). The scale is divided into 2
ranges;
0-5 kV and 0-25 kV maximum deflection. Meter: Class 1.5
Current indication The current display is divided into 5 ranges: 1 µA, 10 µA, 100 µA,
1mA, 10 mA maximum deflection. Currents from 50 nA are
measurable. The current is measured via an operational amplifier
and displayed on a meter: Class 1.5
Plotter output For current recordings, a plotter with a floating input can be
connected to the insulated BNC connector (10). The same test
voltage is available for each current range
(e.g. 0-200 mV).
Built-in battery 12 V, 6.5 Ah operating time at 2/3 load approx. 30 minutes. The
battery is charged by the internal charging unit (instrument must be
connected to mains). The charging time is approximately 24 hours.
0-locking (3) The instrument can be switched on only, when the kV controller (3)
is in the zero position. (Locked against unintentional instrument turn
on!)
Timer (5) 0-30 minutes
Integrated discharge unit Discharge load 2000 Ws (6 µF at 25 kV= accordingly).
Relative humidity not condensing
Ambient temperature working: 0...+45° C
storage: -20...+60° C
