Introduction
About This Manual
This manual introduces you to the CMVA65 Microlog
system. It offers a complete and detailed reference to each
Microlog menu, data screen, and data screen option. This
information is essential when setting up the CMVA65
Microlog and when using the Microlog to collect and
display machinery data.
As you use this manual, you'll discover certain conventions
used:
Bold type is used to indicate text that appears in a
Microlog menu or data screen. Italics are used to
emphasize important information.
 - are used to indicate notes to the reader.
Step-by-step procedures are sequenced using bullets,
•.
 The CMVA65 Microlog may be
configured for either English or Metric
units of measurement. In this manual, all
Microlog setup and display screens
appear with English units.
Chapter Overview
This manual's chapters are organized to help the new
Microlog user quickly set up the Microlog for measuring
specific applications, and to quickly reference the
Microlog's menus, data screens, and options. A chapter
overview follows:

to collect and analyze vibration data from their rotating
machinery, to help reduce costs and downtime.
What is the CMVA65 Microlog System?
A CMVA65 Microlog System (Figure I - 1) consists of
three components:
• A CMVA65 Microlog data collector,
• A host computer with Machine Analyst, or equivalent
software, and
• A support module.


Figure I - 1.
The Microlog System.
The CMVA65 Microlog Data Collector
The CMVA65 Microlog data collector is a lightweight,
portable, data acquisition and storage terminal (Figure I-2).
It collects machinery vibration, temperature, and other
condition monitoring measurements. Together with visual
observations, the CMVA65 Microlog allows for detailed

machine condition analyses in a harsh industrial
environment.

Figure I - 2.
Model CMVA65.
The Microlog performs all the tasks required for machinery
predictive (condition) maintenance. It automatically
collects both dynamic (vibration) and static (process)
measurements from almost any source, it provides easy to
use set up screens for quickly capturing data related to
specific applications like balancing, tracking filter, cyclic
analysis, and current analysis, and it allows the user to
configure up to 12 measurements for automatic data
collection at one measurement point. Using the same
sensor, the user need press only one button to sequentially
collect all pre-configured measurements.
A variety of input devices may be used with your Microlog.
Vibration measurements are collected with a handheld
probe, magnetically mounted probe, permanently mounted
sensors, or from an installed monitoring system.

Introduction
What is the CMVA65 Microlog System?
CMVA65 Microlog Intro - 5
User Manual
Temperature measurements are collected with a non-contact
infrared sensor or with a contact probe.
Values read from other indicators may be entered into the
Microlog by pressing the appropriate numeric keys on the
Microlog keyboard. You can also enter your observations
by typing them in languages or as coded notes.
In addition to its function as a data collector, the Microlog
has all the functions and performances of a powerful
analyzer to capture and display high resolution spectra for
detailed analysis. A Fast Fourier Transform (FFT)
frequency spectrum and a time domain waveform are
available for display on the LCD (Liquid Crystal Display)
screen.
The Microlog automatically turns itself off after 5 minutes
of inactivity to preserve battery life (in all functions except
Analyzer, Transfer, Battery/Temperature, and Reports).
Machine Analyst Host Software
Machine Analyst is an optional support software package
that works with the Microlog to help machinery
maintenance personnel manage machine condition data.
The Machine Analyst host software automatically performs
the tedious clerical work required in sorting and saving
data. Through detailed printed reports, it alerts
maintenance personnel to alarm conditions (exceptions
from normal).
Introduction

What is the CMVA65 Microlog System?
Intro - 6 CMVA65 Microlog
User Manual
Machine Analyst software helps machinery maintenance
personnel to understand the true condition of their rotating
machinery and to base maintenance decisions on the actual
condition of machines.
Machine Analyst software excels in presenting collected
machinery data in statistical and graphic plot format to
obtain useful analysis data (Figure I - 3).

Figure I - 3.
A Machine Analyst Spectrum Display.
Refer to the Machine Analyst software's User Manual for
operational details.
 The host computer has varying minimum
configurations depending on which
Machine Analyst software is used. See
your Machine Analyst software's User
Manual for detailed minimum
configuration information.
The Support Module
The CMVA6112 Support Module (Figure I - 4) is capable
of fast charging the NiMH (CMVA50230-1) battery pack.
Introduction
What is the CMVA65 Microlog System?
CMVA65 Microlog Intro - 7
User Manual

Figure I - 4.

The CMVA6112 Support Module.
There are 2 LEDs and a Deep Discharge button on the
CMVA6112 Support Module. The Deep Discharge button
is used for deep discharging the battery pack in the support
module's pocket. Once deep discharging is complete, the
support module automatically fast charges the battery pack.
The “Battery in Charger” LED indicates the charging
status of the battery pack on the support module, the
“Battery in Microlog” LED displays the charging status of
the battery pack in the Microlog.
The LEDs indicate the battery pack's 3 different charging
modes:
Deep Discharging (Support Module battery only) -
LED flashes slowly.
Fast Charge - LED is ON continuously.
Trickle Charge - LED flashes quickly.
 Reference Appendix A for a detailed
description of battery capacity, care, and
testing.
 The CMVA6112 is powered by an
universal AC/DC adapter. Use of a

different adapter to power the Support
Module should be consulted with the
manufacturer, or the Support Module may
be damaged.
Microlog System Connections

The support module (Figure I - 4) supplied with each
Microlog system provides a convenient, compatible
interface between the Microlog and its host computer
through RS-232 connectors. The support module also
contains the battery charger for the Microlog's batteries.
To connect your Microlog system:
• Using the supplied CMSS50080, CMSS50080-CE
cable, or CMSS250 (25 PIN to 9 PIN adapter
supporting 9 PIN serial ports), connect your host
computer to the support module between the
connection marked COMPUTER on the support
module and one of the serial ports (COM1 or COM2)
on the back of your computer (Figure I - 1).
• Using the supplied CMSS50077 cable, connect the
support module to the Microlog between the connector
marked MICROLOG on the support module and the
25-pin D connector on the top surface of the Microlog
Collector.
• Plug the support module into an AC power supply
through the external transformer adapter supplied with
the support module.
 Before using your Microlog, check to
make sure that the transformer adapter
supplied with your support module is
correct for your electric line supply. The
Microlog uses the same 25-pin D
connector for connection to its various
sensors and to its support module. Keep

The Microlog screen contains three main areas: status line,
working area, and prompt area.
The Status Line

The one-line strip at the top of your Microlog screen is
called the status line (Figure I - 6).

Figure I - 6.
The Status Line.
The status line displays the current date and time (if you
previously set them correctly). The status line also
constantly reports on the percent of free memory available.
Other items of information appear from time to time in the
status line. They are:
• Signal Overload Warning (OV)
• Low Battery Warning (BT)
• Out of Limit Collector Temperature Warning
(TP)
• Shift Lock On up arrow indicator
When the BT (low battery charge) indicator appears, you
have approximately 20 minutes to complete immediate
measurements before the Microlog shuts down to preserve
your data. At this point you can replace the main Error!
