Notes
Note 1 : Specifications apply up to 10% of maximum load current. Above this level, allowance must be
         made for output resistance.
Note 2 : Limited by 50 Ohm output impedance.
Note 3 : 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.


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 between 17°C and 28°C.
Outside this range an allowance of 0.18 x 1 Year Spec. per °C should be added.

Notes
Note 1 : Typical RMS noise figures at 50% of full scale.
Note 2 : Power & temperature sensor on 20A range - microprocessor monitors & protects from overheating.
                 Higher resistance loads allow a longer ON period. See graphs 1 and 2 for details.
Note 3 : Specifications apply to loads of less than 10% of the maximum burden voltage.
Note 4: Zero or floor allowance.

Specifications apply between 17°C and 27°C.
Outside this range an allowance of 0.18 x 1 Year Spec. per °C should be added.

Notes
Note 1: Current limited by 50 ohms output resistance.
Note 2 : 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 3 : Frequency and voltage combinations are limited. See Volt-Hertz profile in Graph 3
Note 4 : Specifications apply up to 10% of maximum load current. Above this level, allowance must be
         made for output resistance.
Note 5 : Zero or floor allowance.


2 Wire output / Remote sensing not available.         Maximum floating voltage : 100V.
Isolation : Floating or grounded selection available as standard.
Specifications apply between 17°C and 27°C.           Outside this range an allowance of 0.18 x 1 Year Spec. per °C should be added.

High Voltage Safety
High voltage output is ramped to allow instruments 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 for frequencies
                up to 5kHz or 3 mins for frequencies above 5kHz. See graph 4.
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.

Notes
Note 1 : Temperature sensor on 30A range - microprocessor monitors & protects from overheating.
            Higher resistance loads allow a longer ON period. See graphs 5 and 6 for details.
Note 2 : Specifications apply to loads of less than 10% of the maximum burden voltage.
