Operation Manual

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.
