Restoring Factory Settings

Making Basic Settings

Selecting the Display Language

Procedure to change the instrument's display language from the available options.

Setting Light Bar Brightness

Adjusts the brightness level of the analog light bar display for optimal visibility.

Setting the Unit of Measurement

Configures the display unit (mm, µm, inch) for measuring values.

Setting the Resolution/Display Format of the Measuring Value

Defines the numerical display format and resolution for measuring values.

Selecting the Number of Features/Test Results to be Displayed

Specifies whether one or two features are displayed simultaneously.

Setting the Light Bar Display Range

Adjusts the scaling and gradation of the analog light bar display range.

Setting the Origin of the Display Range

Sets the origin point (CENTER, BOTTOM, TOP) for the light bar display range.

Assigning Frequently Used Functions onto the MENU Key

Programmable feature to assign up to six functions for quick access via the MENU key.

Positioning the Probe in the Measuring Device (Setup)

Calibrating to Compensate for Probe Sensitivity

Calibrating a Measuring Channel

Procedure to calibrate the zero point and indication values for a measuring channel.

Adjusting Probe Sensitivity (C2 vs. C1)

Adjusts the sensitivity of probe C2 relative to probe C1 for instruments with inductive probes.

Making Settings for Calculating and Displaying Features

Setting the Factor for Correcting the Displayed Value

Enters a factor other than 1 for linking formulas to correct displayed feature values.

Selecting a Channel or Channel Linking (Formula)

Defines the formula for calculating a feature, combining factors and channel inputs.

Selecting Features

Master Measurement

One Point Master Measurement

Compares a single master contact value to a nominal value for correction.

Two Point Master Measurement

Uses two masters to correct probe values and adjust characteristic curve pitch.

Selecting the Type of Master Measurement

Procedure to select between one-point (MAST 1P) or two-point (MAST 2P) master measurement.

Entering Nominal Value for One-Point Master Measurement

Inputting the master workpiece's actual dimension for one-point master measurements.

Performing a One-Point Master Measurement

Steps to perform a one-point master measurement and display deviation.

Entering Nominal Value for Two-Point Master Measurement

Inputting nominal values for the larger and smaller masters for two-point master measurements.

Performing a Two-Point Master Measurement

Steps to perform a two-point master measurement, comparing two masters.

Original Master Measurement

Checks the validity of subsequent master measurements against the original.

Setting Tolerances and Limit Values

Setting Tolerance Limits

Defines the maximum and minimum dimensions a workpiece can have to function correctly.

Setting Warning Limits

Sets warning limits before tolerance limits to recognize trends and prevent issues.

Setting Color of Warning and Tolerance Limits

Configures the light bar colors to indicate compliance or exceeding of warning/tolerance limits.

Setting Plausibility Limits

Restricts the validity range of measuring values to prevent results beyond the measuring range.

Setting Parameters for Recording Measuring Values

Setting Filter Parameters

Filters probe signals to avoid disturbances by setting cutoff frequencies in preset steps.

Specifying the Measuring Process

Selects the measuring mode (NORMAL or AUTOMAT) for workpiece measurements.

"NORMAL" Mode

Continuous measurement mode; START saves value and initiates new measurement.

"AUTOMAT" Mode

Automatic measurement mode; START initiates, START again ends measurement or pause.

Entering a Start Delay

Sets a delay between pressing START and the actual measurement start.

Password Protection

Activating Password Protection

Procedure to set a seven-digit password to protect catalog functions and parameters.

Performing Measurements

Performing a Compound (Sum) Measurement

Measures the thickness of a workpiece by summing probe values.

Performing a Difference Measurement

Measures the height of a step on a workpiece using probe value differences.

Performing a Radial Runout Measurement

Measures radial runout and eccentricity of a workpiece relative to centering tips.

Measuring Value Memories

Working with the Serial (RS-232) Interface

Selecting an Interface Protocol

Specifies the communication method (e.g., ASCII, OPTORSS) for data exchange.

Selecting the Data Transfer Format

Defines data bits, stop bits, and parity check for data transfer.

Selecting the Transfer Rate

Sets the data transfer speed (baud rate) required for communication.

Selecting a Handshake

Configures control signals for data flow control via hardware or software handshake.

Selecting How Data Transfer is Triggered

Determines if data transfer is manual, automatic, or continuous.
