This switch is valid regardless of setting of the range hold switch
and is useful for reading in a different range. Note, however, that
this switch will not operate with the function switch at positions other
than
V
〜
,
V
and
Ω
.
[8] PREPARATION FOR MEASUREMENT
For safe operation, be sure to check the position of the
function switch, terminals to use and condition of
connection of the test leads to the tester before starting
measurement.
When measurement has been completed, be sure to return the
function switch to
POWER OFF
to prevent unnecessary
consumption of the battery. As a countermeasure against a failure
to do this operation, the tester is designed to turn off the power
automatically when its indicator section is closed.
1. Check of the battery
The tester is driven by four dry cells R03. Before starting
measurement, check the remaining capacity. Turn the function
switch to
INTERNAL BATT CHECK
(a range to check the
battery). Then, the pointer deflects toward the right. The
capacity is sufficient when the pointer comes within the range
of
INTERNAL BATT GOOD
at the lowest scale of the scale
plate. If the pointer stops on the left of this range, the dry cells
have been consumed and replace them in accordance with the
procedure described in [15] MAINTENANCE.
2. Zero adjustment of the indicator
If the pointer stays off the 0V line at the left end of the scale
plate, adjust it to the 0V line by turning the zero point setter of
indicator with a screwdriver.
[9] MEASURING OF DC VOLTAGE
Measurement of 0
〜
±
1000V DC (auto range)
Measurement of DC voltage below
±
1000V max.
For safe measurement, never apply a voltage exceeding
±
1000VDC.
Never apply an excessive voltage (more than 100 times the
maximum value of the applicable range) with the range held.
