After recharging the battery pack (see “Charging the Battery” on page 34), you may
need to replace the battery if the instrument only operates when the charger is
connected.
The battery is designed to withstand several hundred discharge-recharge cycles
before failing.
The power indicator only shows the remaining charge level when the charger is not
connected to the instrument.
If you are still unable to turn on the instrument after the charger is connected for
several minutes, the instrument or the charger may be at fault.
15.10 Resolving Measurement Problems
Table 29 Measurement troubleshooting
Symptom Possible explanation
No or weak echoes, no
measurement (LOS)
• Insufficient couplant, especially on rough or
curved surfaces
• Gain set too low
• Material is too attenuating or surfaces are not
parallel or are too rough.
• Gage requires service, try the master reset.
• The echo is too low in amplitude to be
detected. Try increasing the gain.
Strong echoes, no
measurements
• The echo may be in a blank area of the
waveform and cannot be detected.
• The echo is outside of the echo window.
