5.1.4. R PE-2WIRE MEASUREMENT
Measured quantities and display ranges:
Resistance R
PE 0  200  (nominal test current 200 mA)
0  20  (nominal test current 25 A)
Measurement current Im 10  255 mA (nominal test current 200 mA)
0.2  30.0 A ( nominal test current 25 A)
1) Select the R PE-2WIRE measurement by pressing the FUNC hard key first.
2) Check selected test current (200 mA or 25 A) and modify it if needed by pressing the Im NOM (5)
touch-screen key first.
3) Check selected limit value and modify it if needed by pressing the LIMIT (6) touch-screen key first.
Four independent preset limit values are available in STANDARD limit mode selection for quicker
operations. Select the one closest to wished value and modify it by using the + and ― touch screen
keys if needed.
4) Check selected mode (MANUAL or TIMER) and modify it if needed by pressing the MODE (7)
touch-screen key first. In MANUAL mode the measurement will start after pressing the
START/STOP button and will stop after pressing the START/STOP button again. In TIMER mode
the measurement will start after pressing the START/STOP button and will stop after elapsing set
measurement time or after pressing the START/STOP button again.
5) Check the status of test lead calibration and carry out the calibration if needed, see the instructions
in chapter “CALIBRATION OF TEST LEADS” above.
6) Select measurement screen by pressing the (4) touch-screen key and check all settings again.
7) Connect the test leads according to the figure below.
CAUTION
Before connecting test leads to UUT obligatory assure there is no external voltage
higher than 10 V between the test points where test leads will be connected to,
otherwise fuse F4 may blow!

8) Carry out the measurement by pressing the START/STOP button. Test result will currently be
displayed in green (result lower than or equal to set limit value) or in red colour (result higher than
set limit value). Final result will be equipped with green
symbol and with beep-beep sound
(result OK) or with red symbol and with longer beep sound (result not OK) or with yellow
symbol and with beep-beep sound (result OK, but measurement current was too low). See the
display outlook with test result on figure 5 .
9) Save the test result by pressing the SAVE hard key twice, for further instructions see the
“MEMORIZING EXAMPLE” section.
