Note: After connecting the preamplifier or the accelerometer cable to the measurement input, the
screw should be tightened to light resistance only. Do not over tighten this connector!
17.4 RESETTING INSTRUMENT
• SYSTEM RESET: internal software reset clears any setup configuration and brings back the default
factory settings. See Factory Settings (path: <Menu> / Auxiliary Setup).
• HARDWARE RESET: internal hardware reset; no user data is changed. Make sure the battery is not
exhausted, and the unit is turned off. Hold down the <Alt> and <Start/Stop> keys for more than 15
seconds, and then release them. Turn on the instrument as usually.
Note: Hardware reset is only to be used in extreme situations such as an instrument hang-up.
Be aware, that a hardware reset:
- will stop any pre-programmed auto-run modes,
- will stop measurement run!
SVANTEK is committed to continuous innovation path of development, and as such reserves the right to provide
firmware enhancements based on user’s feedback.
To update the instrument firmware:
• Unpack the provided firmware package (provided as a suitable compressed file).
• Make sure the unit is turned off.
• Connect SC 158 cable to the computer and SV 977D instrument (USB interface).
• Keeping pressed the <ENTER> and ▲ keys switch on the instrument - the following message should
appear on the unit's screen: BOOTSTRAP v1.06 (or higher).
• Wait for the message <USB> on the unit’s screen and start from the PC: go-usb.bat.
• The changing number and final message: "..... o.k." should appear on the computer screen.
• Successful firmware update will be indicated by the message: Program loaded!
• Switch off the instrument.
Note: With the use of the SvanPC++ software it is very easy to check if there are any new firmware
releases available for download.
17.6 PRESERVATION OF INTERNAL BATTERIES
• To preserve the life of the internal batteries, it is recommended that the instrument is turned off when it is
stored. In case of alkaline batteries, it is recommended to extract them out of the instrument.
• When the instrument is turned off, it still draws a small amount of battery power. Therefore,
it is recommended to charge the cell every few months if it is not going to be used regularly.
17.7 TRANSPORTATION AND STORAGE
For transportation or storage purpose, we recommend using the packaging provided by the manufacturer. In a
potentially dirty industrial environment, it is advisable to use the carrying case provided by the manufacturer
such as the fabric material case (SA 47), lightweight case (SA 143) or waterproof case (SA 79), which ensures
excellent mechanical and environmental protection and long-term storage conditions.
