(2) Settings for 3-pole measurement
Set the 2/3 pole measurement selector
(
TERMINALS
)to"
3a
".
When using the 3-pole measurement method,
measurement can be carried out with a
measurement frequency of 575 Hz (
3a)or600
Hz (
3b). Normally, you should choose the "3a"
setting. If the galvanometer fluctuates during
measurement, try choosing the "
3b" setting.
This reduces the influence of harmonics earth
voltage and other extraneous earth voltage
components.
(3) Battery check
Set the range selector to
and press the
measurement button (
PRESS ON). If the needle
of the galvanometer is within the
range
of the scale, the batteries can be used for
measurement. Perform this check in the actual
measurement condition, with the measurement
leads already connected.
If the needle of the galvanometer is not within
the "
BATT" range of the scale, the batteries
must be replaced. (See Section 5.2)
