Notes

:

owance must be made for output resistance when driving into a load.

m output impedance. - Low impedance output available

: Internally adjustable from 2mA to 30mA - Factory set to 20mA as standard.

For safety the trip is controlled by a fail-safe circuit independant of the processor which shuts the high voltage
output off in the event of an overload.
Note 4: Typical RMS noise figures at 50% of full scale, bandwidth 1Hz to 10Hz

High Voltage Safety

High voltage output is ramped to allow instrument under test to auto range.
Standby is automatically activated when setting voltages greater than 20V or 200V from a lower voltage.
Standby is automatically selected for high voltage (>20V) after 20 minutes on the same setting.
High voltage (> 20V) output is indicated to user through an audible warning beep.
An external high voltage output/standby control switch is available as an option.

2 Wire output / Remote sensing not available.
Isolation : Floating or grounded selection available as standard.
Maximum floating voltage : 100V
Specifications apply at TCal ± 5°C
Outside this range an allowance of 0.18 x 1 Year Spec. per °C should be added.

Notes

Note 1 : Temperature sensor on 22A range - microprocessor monitors & protects from overheating.
Higher resistance loads allow a longer ON period. See graph 5 for details.
Note 2 : Specifications apply to loads of less than 10% of the maximum burden voltage.

Driving Coils and Inductive Loads

When driving any load exceeding the maximum compliance voltage will cause the calibrator to trip into standby
The maximum compliance voltage on the 10Amp range is specified at a max 2.8V RMS, 7.8V Peak to Peak at 220V supply
Slightly higher compliances are available when powered from a 240V supply.
When using EA002 with leads supplied it is possible to drive 20Amps/50Hz from a 230V supply, falling to 10Amps at 400Hz

Specifications apply at TCal ± 5°C.
Outside this range an allowance of 0.18 x 1 Year Spec. per °C should be added.

Graph 5* : Operating time on 22A range with current into a short circuit at 20°C
Continuous current available up to 10A output.

* Note Timing is started after a minimum period of 7 minutes at zero output.

Shorter periods will reduce the output time availiable.

Due to continuous development specifications may be subject to change.
