“Same” Pre-defined Measurement

configuration is based upon the

highlighted measurement in the

Microlog’s ROUTE mode Its setup

is the Same as the “active”

measurement in the “active”

ROUTE

• Allows you to quickly collect

measurements that are identical to

your “active” ROUTE

measurement, but from various

sensor positions for analysis

purposes

“Opposite” Pre-defined Measurement

• Opposite – setup is identical to the

“active” measurement in the

“active” ROUTE, except it collects

the Opposite data format.

• For example, if the “active” ROUTE

POINT collects FFT spectrum data,

the Opposite non ROUTE

measurement collects time

waveform data, and vice versa

“High Res.” Pre-defined Measurement

• High Resolution – setup is identical to

the “active” measurement in the

“active” ROUTE, except its

Lines/Samples setting is doubled to a

maximum of 12,800 lines.

• For example, if the “active” ROUTE

POINT’s Lines/Samples setting is 400

Lines, the High Resolution non

ROUTE measurement’s Lines/Samples

setting is 800 Lines.

• This allows you to quickly take a high

resolution look at your active ROUTE

measurement

“Accel” Pre-defined Measurement

• Accel – performs a “standard” type

vibration Acceleration measurement

2010-04-21 ©SKF Slide 10 [Code]

“Accel Time” Pre-defined Measurement

• Accel Time – performs the same

“standard” type vibration Acceleration

measurement, but collects time waveform

Averages – 4 (time sync.) if a trigger is

defined for the active ROUTE point, if no

trigger is detected, only 1 average is taken

“Velocity” Pre-defined Measurement

• Velocity – performs a “standard” type

acceleration to velocity vibration

2010-04-21 ©SKF Slide 12 [Code]

“gE” Pre-defined Measurement

• gE - performs a “standard” type enveloped

acceleration vibration measurement.

• Units – Enveloped Acceleration

Display Format - Spectrum

Band pass frequency - gE BPF #3

“Orbit” Pre-defined Measurement

• Assumes

• Input channel – X/Y

Detection – RMS

Lines/Samples – 200 lines / 256 samples

• Displays Orbit Setup screen where

you set the following options:

User-defined Non ROUTE Measurements

• Measurement configuration

remains active until modified,

allowing you to easily re-apply

your user-defined non-ROUTE

measurements

• Default function button – press

to reset all User screen

settings to the factory set

default values of an

acceleration measurement

User-defined Measurement Setup

2010-04-21 ©SKF Slide 16 [Code]

• Change Name – enables you to enter an identifying POINT name and description for

the new user defined POINT

• Display Format – determines how to display the measurement’s data Options are:

Spectrum , Time , Phase , and Orders

• Units – derives the measurement type and units

• Coupling – determines the type of signal acquired for the measurement Options

are: AC , DC , or ICP

• Input Channel – choose from X , Y , Z , X&Y , or Z&Y

• Detection – determines signal detection and scaling Choose from: RMS , Peak ,

Pk-Pk , True Peak , or True Pk-Pk

• Sensitivity – sensor sensitivity

“User” Measurement Options

• Filter – in accordance with Units setting, the drop-down list displays

three types of filter settings, High-pass filter settings, Enveloper

Band pass filter settings, and the HFD measurement setting

• Fmax - enter the FFT upper full-scale frequency, up to 40,000 Hz

• Lines/Samples – determines the resolution of the spectrum

Note - increased resolution requires increased time for data

collection and consumes more storage memory

• Window – the type of window used in the FFT processing

• Averages - determines the number of average samples taken for

the measurement

“User” Measurement Options (continued)

2010-04-21 ©SKF Slide 18 [Code]

• Avg Overlap – overlap processing is advantageous when the time required to gather

a time record is much longer than the time needed to calculate an FFT spectrum (on

GX, occurs at frequencies below 1 kHz) Below 2 kHz, 50% overlap is a reasonable setup.

• Trigger Level – enter a trigger level value

“User” Measurement Options (continued,

still)

• Bin Zeroing – works in conjunction with the High Pass Filter

setting Choose from:

• On – Zeroes everything out below the High Pass Filter setting in the

FFT

• Off – The device does not zero out all recorded FFT values beneath the

selected High Pass Filter value

• It is recommended that you set Bin Zeroing to On, in order to comply with the CMVA60 Microlog’s Low Frequency Cut-off parameter

“User” Measurement Options (continued,

still, again)

dHFD Measurements

• GX supports dHFD measurements (digital High Frequency

Detection), an emulation of HFD measurements supported by the CMVA60 and CMVA65 Micrologs

• Because of differences between the CMVA and CMXA platforms, not all signals will produce identical HFD (CMVA) and dHFD (GX) readings
