4. Main Features:
4.1 Equipment Description

The vPod and vPod II are microprocessor-based vibration meters. Powered by the microprocessor, this family of meters can easily measure average, hold orpeak hold vibration data, and display them with user selectable unit/detection. The batterycharge indicator and sensor bias indicator is also a standard feature of vPod and vPod II.vPod II has built-in memory for storing up to 1000 archive data points. It can transfer datathrough the RS-232C port with a PC.
4.2 Gain and Precision Reading

For those precision machines that have very lowvibration levels, a precision reading is necessary.In addition to an extra quiet accelerometer that issupplied as a standard accessory, both vPod andvPod II incorporate a built-in gain circuit to amplifysmall vibration signals and show the reading inprecision mode when you turn the gain mode on.This one button gain function allows the user toincrease precision by one decimal place.
4.3 Bearing Condition Measurement
Each vPod and vPod II can measure vibration levels in acceleration, velocity or displacement.The users can select to display the vibration results in their preferable units and detections asshown in the photo above. The vPod and vPod II comes standard with a built-in 500 Hz highpass filter. This is significant because most roller element bearings' parts are locatedbetween 500 Hz - 2 kHz. This high pass filter method has been proven to be very useful inidentifying a bearings condition.
4.4 Memory for Data Storage (vPod II)
With the incorporation of built-in EEPROM memory, a vPod II meter can store up to 1000 setsof vibration data. These saved data points can be recalled by entering the meter's REVIEWmode. Every vPod II comes with an RS-232C interface program for downloading the saveddata from memory to a PC for post analysis or report building.
4.5 Optional PDM Software: TRENDEX
Trendex software coupled with the v-Pod II is a cost effective solution to yourmanagement of machine health condition. Until now, most solutions required veryexpensive analyzers and software analysis programs that collected more data thanwas necessary for most basic predictive maintenance projects.
Trendex is setting the new standard in route collection asset management. Withsimple to use one-click reports, downloading pre-defined routes, trending and alarm analysis, Trendex provides a very cost effective strategy to your data collection needs.
Scheduled Measurement- With Trendex, you can easily download predefined routes.Trending and Alarm Analysis:- With Trendex, easily review and display trending plots showing the history of vibration and alarm conditions as well as a percentage ofchange.
Automatic Reports- With trendex, you can build a custom report for simple one click reports.
4.6 Thermo Meter:
The Trendex software supports both vibration and temperature data. In the route datacollection mode, vPod II also can connect to an optional thermo meter for collectingtemperature data.
