5 Minimum and Maximum Value Storage

“MIN/MAX” with Time Stamp

Minimum and maximum measurement values can be stored to

memory with the MIN/MAX function. The most important appli-

cation for this function is the determination of minimum and

maximum values during long-term observation of measure-

ment values. It can be activated for all measuring functions.

Ð Apply the measured quantity to the instrument.

Ð Select the measuring range with MAN|AUTO.

Ð Activate the MIN/MAX function.

Ð Repeated activation of the AVE/MIN| MAX key causes switching

amongst:

MAX > t > MIN > t > MAX ...

The measuring ranges can only be selected manually when the

“MIN/MAX” function is active.

The “MIN/MAX” function is deactivated, and stored MIN and

MAX values are deleted by pressing and holding the MIN/MAX

key (approx.. 1 s), by activating the rotary switch or by switch-

ing the instrument off and back on again.

6 Voltage Measurement

Ð Depending upon the voltage to be measured, set the

rotary switch to

V or V .

Ð Connect the measurement cables as shown. The “V” jack

should be grounded.

Note!

In the 600 V range, an intermittent acoustic signal

sounds alarm if the display value exceeds 600 V.

Attention!

Make absolutely certain that none of the current

ranges are active when the multimeter is connected

for voltage measurements! If the breaking limit val-

ues for the electronic fuse are exceeded due to

operator error, both the operator and the instrument

are in danger! Simultaneous connection to both cur-

rent and voltage measuring circuits is prohibited!
