RANGE
Input channel options
Voltage Input
Internal
The internal voltage attenuator selects the 4mm
connections on the rear of the instrument and has a
max input of 3000Vpk
External Attenuator
(for connection to a HF
shunt).....etc
An External Sensor / Shunt can be connected to the
instrument which will give the operator more
versatility in selecting the Input range required. Note:
if this option is selected then the resulting data is
scaled by the appropriate value within the attenuator
and scale factor sub section. Max input of 3Vpk
Autoranging
Full Autorange
Default setting. Full autoranging will be selected and
implemented within the instrument
Range up only
Selecting this option will allow the test being carried
out to find the highest range via peak detection and
hold on this range. Once this value has been found
another test can be carried out by pressing the
"Trigger" button which will restart from the minimum
value set parameter use for "Low” Frequency
measurements
Manual
Selecting this option will allow the user to set up the
range from the configured measurements available,
this is useful for inrush testing when a mid-analysis
range change is not desirable

Scale Factor
Manually set the scale factor required, normally used
in conjunction with current transformers
