Keyboard Check (Option 19)
1. Connect external keyboard to the TFS3031 (upgraded instruments and
instruments with serial numbers B030000 and above).
2. Three LEDs on the keyboard light up for about two seconds, then turn off.
This indicates that keyboard power is available.
3. Press F1 on the keyboard. This should have the same effect as pressing
softkey 1 (the uppermost softkey) on the instrument front panel.
NOTE
. There are 500 mA available for the keyboard (at 5 VDC). If a keyboard
that draws more power is plugged into the instrument, keyboard power is turned
off. The instrument must be turned off, then back on again to restore keyboard
power.
