Press START/STOP button. The re-
sistance of the protective conductor is
being measured, so its influence on the
test result can be ruled out.
The compensation value
has been measured. is
displayed on the screen,
along with the permanent
symbol. After 3
seconds the tester returns
to measurement mode.
The active test lead com-
pensation is indicated by
icon being
displayed on screen during
the tests of R
PE
(200mA,
10A) and CL I autotests.
The compensation re-
sistance will be taken into
account then displaying
test results of R
PE
.
In order to remove the compensation of the lead resistance (return to default calibration), per-
form the above-mentioned steps with open test lead – icon will disappear and OFF message
will be displayed. After 3 seconds the tester will return to measurement mode.
More messages displayed by the tester are described in section 2.1.2 of this manual.
5 Memory of measurement results
The PAT-2, PAT-2E and PAT-10 testers have memory divided into 10 banks of 99 cells each. Thanks
to dynamic memory allocation, each of the memory cells can contain different quantity of single
measurement results, depending on the needs. That allows for the optimal use of the memory. Each
measurement result can be stored in a memory cell marked with a selected number and in a selected
memory bank. Thanks to this, the user of the tester can, at his sole discretion, assign memory cell
numbers to individual measurement points and the memory bank numbers to individual facilities. The
user may also perform measurements in any chosen sequence and repeat them without losing other
data.
Memory of measurement results is not deleted when the tester is switched off. Thanks to this, the
data can be later read or sent to a computer. The number of a current memory cell or memory bank
is not changed either.
Notes:
- A single cell can be used for storing a complete set of measurement results (including additional
data like limits and pre-set times) for one AUTO test or IEC or PRCD, or a result of a single manual
test (with additional data).
- After entering the measurement result, the ID number of the cell is automatically incremented.
- It is recommended to delete the memory after reading the data or before performing a new series of
measurements that may be stored into the same memory cells as the previous ones.
