METROTOM 1500 (M1500) were the original model when ZEISS began using CT (Computed Tomography) (aka: X-Ray). Then came the M800 and M800 225KV. The M1500 and M800 225KV have the same X-Ray source (with 225 Kilovolts of electricity possible) while the M800 has a smaller one. The 225KV X-Ray sources are expensive and can fail if not properly maintained by a qualified ZEISS Service Technician.  This X-Ray maintenance is called “Periodic Check” and needs to be done every 3 or 4 months depending on the machine usage and vintage of the M1500 or M800 225KV. This will be in addition to an annual Accredited Complete calibration.

The M800 only requires a single Accredited Complete calibration each year because it has a smaller X-Ray source not requiring Periodic Maintenance.  This is considered a Stand Alone calibration so Service Deployment will “process an order” (Aftermarket will assign a TASK to DEP and so they will create an SVO (Service Order) from the purchase order). These are billed (invoiced) like any other calibration (after job completion - triggered by the “95” in CRM).

For M1500 and M800 225KV, being that we are including a calibration plus 2 or 3 periodic maintenance, these are considered a CRM Service Contract.  Right or wrong, these are billed (invoiced) 100% up front. These TASKs must be sent to SVB Service Billing; not Deployment.

METROTOM Rotary Table

All METROTOM models use a rotary table to index the customer's part between X-Rays ("Scans".  However, when quoting the calibration services we do not add a rotary table calibration part number.

When a bridge style CMM (ie: Prismo, Accura, Duramax) includes a Rotary Table (ie: RT-01, RT-AB), that device becomes what we call a “4th axis” in addition to X, Y, and Z.  The RT is “qualified” by the CMM user to assure it is giving exact rotational information and our Service Technicians actually calibrate the RT with a special process.  This takes our Technician more time and requires special skills which is why we add the Rotary Table calibration part number for bridge style CMMs.

Rotary Table are also optional “4th Axes" for O-Inspect.  We do add a RT Calibration P/N for O-Inspect having an RT.

The RT is simply an integral component of all METROTOMS so all of our Technicians certainly have the skills to perform whatever service is necessary.  There is no option to calibrate a METROTOM without the RT and the single METROTOM calibration prices factor in all work required so no need to add an RT calibration part number for METROTOMs.

The newer M1 and M6 Scout also do not require a separate RT calibration part number.
