4.5 Resistance Measurements
Resistance is measured with DC
voltage from the 1.5 V mignon cell.
The table of measuring ranges in
chapter 5 gives the maximum mea-
suring currents for full deflection and
a battery voltage of 1.5 V.
Socket polarity is as follows:
Positive pole on socket „⊥“
Negative pole on socket „Ω“
➭ Set range switch, depending on
the measured value expected,
to one of the ranges Ω x 1 ...
Ω x1000.
➭ Plug in the test leads to sockets
„⊥“ and „Ω“.
➭ Short-circuit the test leads.
➭ Using the potentiometer knob, set the pointer of the measur-
ing mechanism to full deflection 0 Ω. If it is no longer possi-
ble to set for full deflection or if the reading does not remain
constant after setting, the mignon cell is depleted or the pig-
tail fuse is defective.
➭ Connect resistance to be measured R
x
to the test leads.
