Maintenance
1 Occasionally oil the steel portions of the instrument, screws, spacer rods,
nuts, etc.
2 Care should be taken in handling the device in order to avoid any misalignment
of parts.
Data Acquisition Setups—
You can fully automate your test data collection by using one of these
MiniLoggers. The MiniLogger is a simple-to-use, four channel, stand-alone
data-logging system, which can collect data generated from digital indicators
or LSCT transducers. Use model HM-2325A.3F for LSCTs and HM-2330D.3F for
Digital Indicators.
Features include:
• Four channels with real-time data acquisition
• Backlit LCD display
• RS232 interface for computer or printer.
• Nonvolatile test data storage and instrument calibration
• Battery-backed real-time clock
• Auto conversation of instrument calibration between
English or Imperial units and SI or metric units
• View logged test data via the LCD display
