4.6 Frequency measurements (FrE)
Connect the voltage measurement tip EXM 72010 to
the 7-pin universal connector.
The measurement range serves for measurements of
frequencies in the range of 0,1 Hz – 10 kHz with
voltages > 5 V. A selection between Hz and kHz
occurs automatically after attaching the test prods.
Note:
While the device is in open-circuit operation the
display may show 0,00 Hz/kHz ±1 digit.
With low frequencies the measurement signal needs
to be placed for a few seconds before it indicates a
reliable value.
The automatic shout-down can be deactivated by
interfering signals, e.g. because of low frequencies
with attached measurement tips.
4.7 Temperature measurements with TMZ 25
(T ashes)
Measurements with the intrinsically safe TMZ 25 and
a Fe-CuNi-sensor are only permissible in Ex I- and Ex
II-areas. Connect the TMZ 25 to the 7-pin universal
connector and plug temperature sensor on the TMZ
until it’s catched.
With the TMZ 25 you can measure temperatures bet-
ween – 80 and + 600 °C. The optimal measurement
range is selected automatically.
Note:
With the universal sensor indication on the display is
rst readable after approx. 30 s, with surface sensors
after approx. 10 s. Special sensors can be delivered.
