Sat: When the photodiode current exceeds 1mA, and the
detector starts to saturate, or the pyroelectric voltage
exceeds the maximum, the message "sat” (=saturated) is
displayed
.
9.5 Troubleshooting
9.5.1. Vega Meter
Problem
Cause/Remedy
Instrument will not operate after
being completely discharged
and connected to charger.
Check that charger provides
200mA.
Instrument operates with
charger but not with battery
alone.
Battery is low. Recharge
overnight with the Vega turned
off for 7-8 hours. If the Vega still
doesn't work with battery, then
the NiMH battery is probably
dead. Replace battery (see
section 9.6.1.4).
9.5.2. Thermal Sensors, Energy Measurements
Problem
Cause/Remedy
Instrument triggers on
background noise or
sometimes fails to catch large
pulse.
Increase threshold level; See
Section 4.5.3
Instrument does not show
ready for a long while after a
reading is made.
Increase threshold level; See
Section 4.5.3
Non-reproducible results when
measuring very small energy
pulses; or no response to
pulses at low energy.
Decrease threshold level: See
Section 4.5.3
