Micro II Readouts incorporate backlit LCD displays that flag out-of-tolerance conditions by changing color from green to red. Seven decade digital displays show actual feature sizes or deviations from nominal sizes. They also include analog bargraphs to graphically display the test piece condition relative to the product limits. Auto-Zero and Auto-span setting features make these instruments very operator friendly. RS-232C serial data and process control outputs are standard.

Micro II model AEQ 40-11-60 with single master type air probe and master ring provides fast and accurate inspection of internal diameters.

RS-232 serial data ports are standard on all Micro II's. Model AEQ 40-11-10 with Air probe connected to Mini-Printer model IMP- 24 via the RS-232 port is shown at the right.

 

Multiple inputs with single display -- Auto-elect models direct multiple inputs to a single display. As gages are sequentially inserted in the workpiece, the readout automatically senses the active gaging member and displays the reading. Up to four air gages or pairs of LVDT inputs can be connected to a single display. Micro II model AEQ 40-11- 60 is shown at the to the right.

LVDT Readouts -- Factory installed interface modules provide the capability to operate LVDT type inductive probes. (See inductive probes on pages 34 &35). Model AEQ 40-11-E2 is shown at the left.

Multi-channel Micro II readouts come with up to four input channels which can be configured for operation with either dimensional air gages or LVDT electronic gaging cartridges.

Model AEQ32N-60 connected to an Air probe and Air ring gage with Guide chute is shown above. See Guide chutes on page 23.

Dual Input Micro II models with three displays provide fastaccurate inspection of the internal and external diameters of mating parts. The upper display shows the I.D. size, the middle display shows O.D. size, and the lower display shows the calculated clearance between the parts.

Model AEQ32N-60-E2 with air probe and Vee gage incorporating inductive probes. See page 34 for more on Vee gages with guide chutes.

Digital display
Red-green backlited, 7 decade, LCD shows actual part sizes. Digital resolutions are set according to the Hi & Lo product limit span -- see table at bottom of page.

Bargraph display
Red-green backlited, 81 segment bargraph, graphically displays the workpiece size and acceptance limits.

Out-of-tolerance Indicators
O/T conditions are flagged by changing the displays from green to red.

Auto-Zero feature (single master)
Micro II readouts configured for single master operation have their sensitivities set at the factory using master standards. These instruments are zeroed by the user placing a setting master on the gage and pressing the center key to Auto-Zero the readout.

Auto-Span feature (dual master)
Users set the sensitivity, and zero on Micro II readouts configured for dual master operation using Min & Max setting masters. Pressing the center key starts the Auto-Span setting cycle with prompts for the user to sequentially place the setting masters on the gaging member; the sensitivity and zero are then set automatically.

Features, front panel:
Gage 1X -- Sets Hi/Lo limits at 50% of full scale.
Gage 2X -- Sets Hi/Lo limits at 25% of full scale.
Hi/Lo -- Inputs product acceptance limits.
Master -- Inputs master sizes.
Print button -- Transmits serial data output.
T.I.R. mode button -- Activates T.I.R. mode on single channel readouts, indexes active channel on multi-channel readouts.
Arrow key array -- Navigates set-up data, and activates Auto-Zero & Auto-Calibration cycles.
Pneumatic Zero adjust (On air gage modules only)
Air Status indicator -- indicates correct air pressure.

Gage inputs, specify from 1 to 4 input modules per enclosure:
