Power Supply Operating Instructions - Fluke i50s User Manual

•
Simultaneous flashing of all LEDs
All the LEDs flash simultaneously for five seconds when the auto zero has
not been carried out correctly. Two reasons can cause this phenomenon:
1. The Probe is strongly magnetized
2. The primary current is present during the auto zero function
The Probe reverts to the state preceding the request, i.e., an auto zero has
not been performed but measurement of the current remains possible.

Power Supply Operating Instructions

To avoid damaging the Power Supply, use the following
guidelines:
•
Do not disconnect the protective ground.
•
The mains plug must be connected to a mains voltage
supply with a ground terminal.
To operate the Power Supply (see Figure 4):
1. Select the appropriate mains voltage 230 V or 115 V ac using the voltage
selector switch located on the back panel.
2. Fit the rated fuse appropriate to the selected mains voltage.
3. Connect the Power Supply to the mains supply.
4. Connect the Probe(s) to the RJ45 sockets located on the front panel of the
Power Supply.
5. Operate the ON/OFF switch on the back panel. The front LED will
illuminate to indicate that power is being supplied to the Probe(s).
