Accuracy:
+/- 0.02% of setting, +/- 0.005% of range, +/- 0.2nA
Voltage Capability:
15V with new batteries or mains power
(11V with minimum allowable battery level)
Regulation:
Load: Better than 5ppm per Volt
Supply: Better than 5ppm per Volt
Output polarity:
Positive or negative switch selected. A centre off position
provides an open circuit on the output terminals
Out of limit warning:
A front panel indicator provides a warning of insufficient
drive voltage
Output stability:
Less than 30 ppm per °C (0°C to + 50°C)
Less than 10 ppm per hour at constant temperature
Less than 75 ppm per 6 months
Output noise:
100, 10 and 1mA ranges: less than 5ppm of full scale
100 and 10uA ranges: less than 10 ppm of full scale +/- 0.1nA
Null sensitivity:
Adjustable from +/- 25 mA to +/- 25uA FSD via front panel
control. Maximum resolution is 0.5uA.
Power supply:
Time Electronics power unit type PU2 which is housed in the
rear of the 1024. The PU2 will power the 1024 direct from the
mains or an internal rechargeable battery. The battery is
automatically charged when mains power is connected.
