8. Making measurements with the
01
8. Preparations for making measurements
Operate and store the
01
only at the specified storage and oper-
ating temperatures conditions. Avoid continuous insulation.
- Check rated voltage and rated current details specified on the safety meas-
uring lines. The nominal voltage and current ratings of the safety measuring
cables included in the scope of delivery correspond to the ratings of the
01
- Check the insulation of the safety measuring cables. Discard the safety
measuring cables immediately if the insulation is damaged.
- Check safety measuring lines for continuity. If the conductor in the safety
measuring line is interrupted, the safety measuring line must be quaran-
tined immediately.
- Before - at the rotary switch
- a different function is selected, the safety
measuring lines must be disconnected from the measuring point.
- Strong sources of interference in the vicinity of the
01
can
lead to unstable readings and measuring errors.
8.2 Voltage and current measurement
Do not exceed the maximum permitted voltage with respect to
earth potential! Electrical danger!
The highest voltage which may be applied to the jacks,
- COM socket
- jack for V,
, Hz, °C,
- jack for mA range
and the
- jack for 10 A range
of the
01
against ground, amounts to 1000 V.
