Current Measurement

➭

First switch off the power supply to the measuring circuit
or the load component and discharge any capacitors
which might be present.

➭

Select range A

with the rotary switch for currents

> 300 mA, or range mA

for currents < 300 mA.

Switch to the measuring range A first

, for the measure-

ment of currents of an unknown quantity.

➭

Select the respective current type which corresponds to
the measured quantity by briefly pressing the multifunc-
tion key

ESC|FUNC

. Each activation of the key causes

alternate switching between DC and (DC + AC), as well
as acknowledgement by means of an acoustic signal.
The symbols DC and DC AC indicate the selected volt-
age type at the LCD display.
After the range has been selected with the rotary switch,
the DC current mode is always active. If the multifunction
key

ESC|FUNC

is activated, the instrument switches to

DC AC, which is acknowledged with an acoustic signal.

➭

Securely connect the instrument to the load component
in series as shown (without matching resistor).
