Making Scale Transfers (Scale)
The Scale operation emulates a transducer by helping you to
convert the measured readings proportionally to the
specified ratio and unit display. Use Scale to transfer voltage
readings to proportional readings when using clamp- on
current probes or high voltage probes. The available scale
conversions are shown in the table below.
1 Press and hold for more than 1 second to enable
the Scale operation.
2 The most recently saved (default: 1 kV/V, ×1000.0) ratio
and unit will be shown on the primary and secondary
displays. Press while the SCALE symbol is flashing
to cycle through the available ratio and unit displays.
3 Press while the SCALE symbol is flashing to save the
selected ratio and unit and start the conversion. The
selected ratio and unit will be used as the default ratio
and unit the next time Scale is enabled.
4 Or, while the SCALE symbol is flashing, if no activity is
detected after 3 seconds, the conversion will begin (with
the specified ratio and unit shown on the primary
display).
5 Press and hold for more than 1 second to cancel
the Scale operation.
