Test Sequence for Alternative Measuring Method

➭ Set the rotary switch to the I

position.

➭ Select the Alternative measurement type:

– By setting the parameters

– Via the MA key

➭ Set the Up(set) and frequency parameters.

➭ Connect the DUT’s mains plug (protection class I) to the test

instrument’s test socket (see figure 4/4).

➭ Start the test: press the START/STOP key.

➭ Switch the device under test on.

➭ The measured values are displayed. The measured

value recording symbol shown at the right appears.

Each time this key is pressed, the currently displayed

measured value is saved to the buffer.

➭ Stop the test: press the START/STOP key.

The save symbol appears (floppy disk showing the

number of measured values stored to buffer memory)

and prompts you to save the measured values to an ID

number.

➭ Read the measured values and compare them with the

table of permissible limit values.

➭ Press the ESC key in order to discard the measured

values stored to buffer memory and acknowledge by

pressing the key shown at the right.

Maximum Permissible Limit Values for Leakage Current in mA

* For devices with heating power of greater than 3.5 kW

the protective conductor, and which comply with requirements for touch cur-

rent and, if applicable, patient leakage current, e.g. computer equipment with

shielded power pack

Note 2:Permanently connected devices with protective conductor

Note 3:Portable x-ray devices with mineral insulation
