Power
Failures
A power failure caused by a temporary drop in
line voltage results in one of two responses by
the TMA 2940 CE:
• If the drop is fairly large and of long duration
(20 milliseconds or more), the system will
reset and go into its power-up sequence
when power resumes.
• If the drop is small or of short duration, the
system may halt, and you may see “ERR
F02” on the display. This message means
that the system has detected a power failure
and has shut down. The instrument will not
restart until reset. To reset, press the Reset
button on the TMA 2940 CE's back panel.
If “ERR F02” appears at startup and remains
even after you have tried to restart the instru-
ment, the detection circuitry itself is probably at
fault. Do not try to repair it yourself; call your
TA Instruments service representative.
The TMA 2940 CE is designed for a nominal line
voltage of 120 volts AC (± 10%), 50 or 60 Hz. It
should not be operated outside this range. Low
line voltage may result in poor instrument
operation; high line voltage may damage the
instrument.
