The instrument will request conrmation if it is recording or metering energy,
recording transients or alarms, or capturing an inrush current.
If the power-o󰀨 command is conrmed, the recordings will nalize, and the
instrument will turn o󰀨. Recordings will automatically resume the next time that
the instrument turns on.
If the instrument is o󰀨 while connected to external power, the battery will charge.

2.9 INSTALLING THE COLOR CODES
To identify the cords and the input terminals, you can color-code them using the
colored markers provided with the instrument.
1. Break o󰀨 the sector and insert it into the two holes near the terminal. The
large sectors are for the current terminals, and the small sectors are for the
voltage terminals.
2. Clip two rings of the same color onto the ends of the cord that will connect
to the terminal.
You have 12 sets of di󰀨erent-colored markers to match the instrument with the
color codes in e󰀨ect.
Large sectors for current terminals Small sectors for voltage terminals
The same color as
the terminal
