A danger arises when ever the current flow through the test object is interrupted. In this case, an extremely
hazardous voltage is induced in the test object. Therefore, particular caution is required when the test object
is being disconnected from the RESISTOMAT
®
model 2329 or if the contacts slip off or drop while energy is
still stored in the test object. As the RESISTOMAT
®
model 2329 does not indicate the level of this energy, the
test object must be short-circuited prior to disconnection in order for it to discharge fully.
For safety reasons, inductive test objects must not be unplugged from the device.
If a partially or fully grounded inductive test unit is unplugged from the device, a voltage flashover might occur
in the plug, thus exposing the operator to the flow of current in the electrical circuit of the test object. This is
extremely hazardous !
Great care must be exercised if the RESISTOMAT® model 2329 exhibits abnormal behaviour.
For example: No response to actuation of controls;
No supply of measurement results;
Unusual displays.
In such cases, always short-circuit the inductive test object and then disconnect it.
2. General Information
2.1 Safety
DANGER
Special caution is required in the case of inductive test devices!
If
-
the plugs are pulled out of their sockets,
-
the measurement current is switched over,
-
the cables tear,
-
the terminals on the test device are loose,
-
the unit is switched off during measurement,
-
the power is interrupted during measurement,
-
the measurement current changes for any other reason:
then
extremely dangerous inductive voltages can be generated
under these physical conditions!
