Carrying out Measurements

6.4 AC Voltage Measurement

Never apply voltages exceeding 300V to input
sockets.

Connect mains lead (13) to the mains connec-
tor

Select function VAC via the function switch (17)

Select the contact voltage by means of key (15)
in display

Connect the the test leads /mains plug to UUT

Read the measurement result on the display

If the voltage exceeds 300V, the message "At-
tention (1) + Limit (2) " is displayed. In this in-
stance, immediately disconnect the measure-
ment instrument from UUT.

Also refer to chapter 7.0.

No possibility to store the measurement re-
sults.

6.5 Frequency Measurement

Never apply tvoltages exceeding 300V to input
sockets.

Connect the mains lead to the mains connec-
tor (13)

Select the function f via the function switch (17)

Connect the the test leads /mains plug to UUT

Read the measurement result on the display

Also refer to chapter 7.0.

No possibility to store the measurement re-
sults.

6.6 Contact Electrode

Measurement of the present contact voltage is car-
ried out after setting the contact voltage limit. By
touching the contact electrode, exceeding the limit
is automatically indicated (>25V or 50V).
