SKF Microlog GX Series - Collecting Data Screen with Running Speed Options; To Manually Enter the RPM

Non ROUTE
How to Collect Pre-set Non ROUTE Measurements
ICP – Acquires the input signal from a charge amplified sensor.
Sensitivity – Use the alphanumeric keypad to enter transducer sensitivity in millivolts
(mV) per Engineering Unit (EU). 100 mV/EU is used for most acceleration sensors, 200
mV/EU for most non-contact displacement sensors, and 1,000 mV/EU if the input is
volts and the scale is to be read directly.
Trigger - When the Trigger is set to Off, the Microlog prompts you to manually specify
the RPM for orbit measurements, rather than taking a real-time RPM reading using a
tachometer.
 Refer to To manually enter the RPM, below, for details.
Ext. Trigger Slope – Select plus or minus to determine whether the trigger occurs on a
rising or descending signal.
[+] – triggers on an ascending signal.
[-] – triggers on a descending signal.
Trigger Level – Enter a trigger level value in the text field and press an Enter button.
 If the Configuration screen Trigger Level setting is set to
Automatic, the Trigger Level setting reads “Automatic” and
cannot be set.
To manually enter the RPM:
• From the Orbit Setup screen, use the up/down arrow buttons to highlight the
Trigger option and press the right arrow button. A drop-down list appears.
• Use the up/down arrow buttons to select Off and press an Enter button.
• Finish making any other setting adjustments to the Orbit Setup screen, and press
an Enter button. The Collecting Data dialog displays with a prompt to specify the
running speed at the bottom of the page.

Collecting Data Screen with Running Speed Options.
There are three options for entering the RPM when the Orbit Setup screen’s Trigger
value is set to Off:
dBase - Take the RPM value from the database if previously assigned to the POINT.
 This option only appears if the currently selected POINT in ROUTE
mode has a speed entered.
Type In - Type in the value using the numeric keypad, or
Spec - Select the 1X RPM frequency from the spectrum display.
• Press the dBase button to use the RPM value previously assigned to the POINT.
