Install the stylus  into the probe body.
Use the stylus installation tool  to tighten the stylus  into the probe body .
Turn the tool until the stylus is snug.
Use a coin or flat-head screwdriver to remove the battery compartment cover .
Install batteries  into the battery compartment.
Install the battery compartment and tighten the cover.
If the probe is not yet installed to the toolholder, follow the below steps, otherwise skip to Step 3:
Loosen the all the set screws in the probe toolholder .
Insert the probe body  into the toolholder .
Use the hex wrench  to snug the (2) top set screws.
Insert the OMP40-2 probe into the spindle.
Place an indicator  onto the center of the stylus ruby.
Manually turn the spindle to measure the radial runout, not to exceed 0.0002" (5µm) total indicated runout.
Use the hex wrench  to adjust the (4) adjustment set screws and set the runout.
Make sure all (6) set screws are snug into the probe when finished setting the runout.
Place the retainer strap  over the shaft mount on the probe body .
Install the shaft  into the shaft mount. Snug the shaft with the open-end wrench.
Place the stylus  into the stylus mount . Snug the set screws with the screwdriver.
Bend the retainer strap 90 degrees as shown .
Place the stylus assembly onto the probe shaft. Snug the set screws with the screwdriver.
Attach the retainer strap to the bottom of the stylus assembly using included screw .
Install the tool probe to the table:
Loosen the (6) set screws  around the probe body.
Remove the base  from the probe body.
Use a 3/8" - 16 x 1 socket head cap screw  to anchor the base to the machine table.
Place the probe body on the base.
Snug the (4) base mount set screws .
Snug the (2) base rotation set screws .
Set the direction of the OTS tool probe:
Macro variable 592 changes the radius offset direction. Change macro variable 592 to make sure the tool does not hit the probe body when it moves off center to compensate for the tool radius.
When you use the WIPS calibration pages to calibrate the probe, this will automatically sets macro variable 592 to 2.
When you use VQC calibration pages to calibrate the probe, you can select 2 or -2 for macro variable 592.
If the probe is installed in a different direction, you must change macro variable 592. This lets the tool move away from the probe during the rotating tool length cycle.
Set macro variable 592 to agree with the direction of the probe. These are the correct values:
#592 = 1.0, diameter along the X Axis setting: rotating length cutter radius offset setting in the Y- direction.
#592 = -1.0, diameter along the X Axis setting: rotation length cutter radius offset setting in the Y+ direction.
#592 = 2.0, diameter along the Y Axis setting: rotating length cutter radius offset setting in the X- direction.
#592 = -2.0, diameter along the Y Axis setting: rotation length cutter radius offset setting in the X+ direction.

This procedure applies to NGC machines built after April 2017 or NGC machines with Software Version 100.17.000.1012 or greater.
Assemble OMP40-2 probe per procedure OMP40-2 Probe - Installation and verify that the toolholder probe is within 0.0002" TIR before calibrating.
Go to  Edit>VPS>Probing>Calibration>Complete Probe Calibration 
Follow onscreen instructions to setup tools and then run Complete Probing Calibration in MDI.
Select the WORK PROBE CALIBRATION tab.
Put the work probe  into the spindle.
Measure the length  of the work probe. Enter the length of the work probe.
Enter the diameter of the ball at the end of the work probe. For the standard Renishaw probe, use 0.2362" (6 mm).
Measure the inside diameter of the ring gauge. Use an inside micrometer or a bore gauge. If the inside diameter is written on the gauge, use that number.
The calibration box shows COMPLETED.
