6 Making Basic Measurements
This section describes how basic measurements are made, i.e. single measurement mode
without post-processing of the results.
6.1
Scale Length
The scale length is ±120,000 for all measurements except frequency (full scale 12,000) and
capacitance (full scale 1200).
{OFL}
is displayed when the range maximum is exceeded.
Note, however, that safety considerations limit the maximum voltage and current that can be
measured to below the scale length maximum.
6.2
Measurement Parameter Selection
Refer to the front panel diagram in
section 5.1
The two rows of darker grey keys below the display directly select the measurement
parameters for either the primary or secondary display. When pressed alone the parameter
keys select the measurement parameter for the primary display, cancel any secondary
functions, and set the range to auto-range.
Pressing
[2nd]
followed by a parameter key selects the parameter for the secondary display;
this is explained fully in Dual Measurement Mode,
section 8
, which also details the
combinations of parameters that can be used.
Additional parameters marked in blue above certain keys are selected by first pressing
[SHIFT]
.
Whilst shift is operational a
{SHIFT}
symbol appears on the left side of the display.
See
section 7
for full details.
6.3
Measurement Range Selection
Refer to the front panel diagram in
section 5.1
, and to the display diagram below
.
When a parameter is first selected, auto-ranging is enabled and an
{AUTO}
symbol is
displayed. Pressing either of the
[

]
/
[v]
arrow keys (
Range+/Range-
) cancels auto-ranging
whilst leaving the range set to its existing value. The
{MAN}
symbol is displayed and further
presses then change the range upwards or downwards. Pressing
[OK]
returns the instrument
to auto-ranging operation.
The units appropriate to the function and range (e.g.
{mV ac}
) are shown to the right of the
display. When the secondary display is not being used to show measurement values, the
selected range is shown there.
Note that the 10A range, which uses a different input socket from mA measurements, can only
be selected manually. Once 10A has been selected, however, this setting will be retained for
current measurement until it is returned to mA.
Note that the
{AUTO}
and
{MAN}
symbols apply only to the primary display.
