4.1.1 Measuring in the Range up to 50
Ω
(
Ω
x 1, red)
➭
Set the range selector switch (1) to
Ω
x 1 (red marking).
➭
With the rotary knob (2), adjust the pointer to full-scale
deflection (
∞
) on the
red
scale.
➭
Connect the unknown resistance R
x
to be measured
and read the resistance value on the
red
scale.
4.1.2 Measuring in the Ranges up to 1 M
Ω
(
Ω
x 1/10/100/1000, black)
➭
Set the range selector switch (1) to one of the measur-
ing ranges
Ω
x 1 ...
Ω
x 1000, depending upon the re-
sistance value to be measured.
➭
Short-circuit the measuring leads.
➭
With the rotary knob (2), set the pointer to full-scale
deflection (0
Ω
) on the
black
scale.
➭
Connect the resistance R
X
to be measured to the mea-
suring leads and read the resistance value on the black
scale. The indicated value must be multiplied by the
specified factor in line with the selected measuring
range.
