5.8.5. U RES MEASUREMENT
Measured quantities and display ranges:
Residual voltage on power plug U RES 10  460 V AC or 10  650 V DC
Residual voltage on internal components U RES 10  460 V AC or 10  650 V DC
Input requirements:
Input voltage U
IN (READY condition in PLUG mode) 43  460 V AC
Trigger voltage U TRIG (READY condition in INT mode) 100  460 V AC
1) Select U RES function by pressing the FUNC key first.
2) Check selected mode and modify it if needed by pressing the MODE (4) touch-screen key first.
3) Check selected connection and modify it if needed by pressing the CON (5) touch-screen key first.
INT 4-WIRE mode is selected:
4) Check selected limit time and modify it if needed by pressing the LIMIT t (6) touch-screen key first.
5) Select measurement screen by pressing the (3) touch-screen key and check all settings again.
6) Connect test leads according to one of the figures below.

7) READY, DISCONNECT UUT message will appear when U TRIG voltage within required range 100
 460 VAC is present. Carry out the measurement by disconnecting UUT. Disconnection of UUT
according to the figure 33 means disconnection of multiple plug adapter. Disconnection of UUT
according to the figure 34 means turning off mains switch.
