Machinery Balancing Module
How to Set Up the Microlog for a Single-Plane Procedure
The Variable sensor option allows you to configure settings for a
sensor that is not on the sensor list.
Typically, accelerometers are used to perform velocity
measurements for field balancing procedures.
A Manual Entry option is available at the end of the list for
manual balancing data entry, allowing you to review and change
balancing run data. If selected, you are prompted to manually
enter the running speed, vibration magnitude, and phase angle
for the balancing runs.
Sensor Units – (Not editable if a preconfigured sensor is selected in the Sensor field.)
When the Variable sensor is selected, select the measurement units to use for the type
of sensor being used. Options include g, in/s, or mil.
Sensitivity – (Not editable if a preconfigured sensor is selected in the Sensor field.)
When the Variable sensor is selected, use the alphanumeric keypad to enter transducer
sensitivity in millivolts (mV) per Engineering Unit (EU).
Input Range – (Available only if the system Setup menu’s Input Range setting is set to
Sensor Units.) Select the signal input range as a fixed range in transducer units in a 1
- 2 - 5 sequence. (The available fixed values vary depending on the transducer type
being used.)
If a fixed range is selected and the Microlog detects an over range,
it automatically selects the next higher range until it does not over
range.
ICP Power – (On or Off), (Not editable if a preconfigured sensor is selected in the
Sensor field.) When the Variable sensor is selected, select to turn ICP power Off or On
for the sensor.
Display Units – Specify the unit of measurement for the select sensor type. The
options available in the list vary depending on the sensor selected.
Detection – Determines signal detection and scaling. Detection options include Peak,
Pk-Pk, and RMS. The default setting is Peak for acceleration and velocity, and Peak-
to-Peak (Pk-Pk) for displacement.
Weight Units – Select the units of measurement used for your trial, correction, and
trim weights. Options include: g, kg, cm, mm, oz, lb, in, EU or %.
Length Units – Select the units of measurement used for measuring the radius of the
weight placement (from the shaft center to the position of the weight). Either inch,
feet, EU. This information is used if you wish the Microlog to estimate your trial weight
for you.
Trigger – Manual or Visual. (Available only if the Setup screen’s Trigger field is set to
User.) Determines how the trigger level is entered when setting up measurements that
require a trigger, either manually as numeric input in the subsequent Trigger Level
field, or visually using a graphic representation of the trigger signal and trigger level.
Manual – When set to Manual, you will enter the trigger level in volts as
numeric input in the Trigger Level setup field.
