Current Measurement; Diode Testing - ZA-TEC ZA 6-2 Bedienungsanleitung

rated voltage and current of the ZA-TEC ZA 6-2.
- Check the insulation of the safety measuring leads. If the insulation is dam-
aged in any way, do not use the leads.
- Check the continuity of the safety measuring leads. If the conductor in the
safety measuring lead is interrupted, do not use the leads.
- Before selecting another function with the rotating switch  , always discon-
nect the safety measuring leads from the measuring point.
- Sources of strong current in the vicinity of the ZA-TEC ZA 6-2 may cause
unstable or incorrect readings.
8.2 Voltage and current measurement

Always observe the maximum voltage to earth potential!
Electrical hazard!
The maximum voltage which may be applied to the sockets
- COM socket 
- socket for V, Ω,
- socket for 10 A range L
of the ZA-TEC ZA 6-2 to earth is 1000 V CAT III.
8.2.1 Voltage measurement
- With the rotating switch  , select the desired function ( ,
ZA-TEC ZA 6-2.
- Connect the black safety measuring lead to the COM socket  on the
ZA-TEC ZA 6-2.
- Connect the red safety measuring lead to the socket  on the
ZA-TEC ZA 6-2.
- Connect the safety measuring leads to the measuring points. Read the meas-
urement value displayed in the digital display  of the ZA-TEC ZA 6-2.

Current measurement

- With the rotating switch  , select the desired range and function (A AC/DC
or µA AC/DC) on the ZA-TEC ZA 6-2.
- Connect the black safety measuring lead to the COM socket  on the
ZA-TEC ZA 6-2.
- Connect the red safety measuring lead to the jack for the A range L (up to
10 A AC/DC) of the ZA-TEC ZA 6-2.
- Connect the safety measuring leads to the measuring points. Read the
measurement value displayed in the digital display  of the ZA-TEC ZA 6-2.

8.3 Resistance measurement
- With the rotating switch  , select the desired function (Ω,
ZA-TEC ZA 6-2.
- Connect the black safety measuring lead to the COM socket  on the
ZA-TEC ZA 6-2.
- Connect the red safety measuring lead to the socket  on the
ZA-TEC ZA 6-2.
- Connect the safety measuring leads to the measuring points. Read the meas-
urement value displayed in the digital display  of the ZA-TEC ZA 6-2.
See fig. 6:

8.4 Diode testing

- With the rotating switch  , select the desired function (
ZA-TEC ZA 6-2.
- Using the blue key  on the ZA-TEC ZA 6-2, switch to diode testing (
- Connect the black safety measuring lead to the COM socket  on the
ZA-TEC ZA 6-2.
- Connect the red safety measuring lead to the socket  on the
ZA-TEC ZA 6-2.
- Contact the diode connections with the safety measuring leads and read the
measurement value displayed in the digital display  of the ZA-TEC ZA 6-2.
- For a normal silicone diode located in flow direction, the flow voltage
between 0.4 V and 0.8 V is displayed. If "000" appears in the display, there
may be a short circuit in the diode.
- If no forward voltage is detected, first check the polarity of the diode. If still
no forward voltage is displayed, the forward voltage of the diode is beyond
the measuring limits.
