1.0 PRECAUTIONS AND

GENERAL INFORMATION

All Max

µµ

m



III Models: Your new

Max

mIII Digital Electronic Indicator will

provide both Standard and Enhanced

measurements. When placed in the

Enhanced Mode, the Max

mIII provides

the capability of measuring relative

maximum, minimum and T.I.R. values

Max

mIII units come with battery

installed and operate in the traditional

Standard Max

mMode. When not in use

the Indicator or Indicating unit is left in its

“Sleep” mode which conserves battery

power. (Ref. Section 2.1)

The unit also includes removable overlays

for duplication of the previous Max

mand

Max

mPlus model design where needed.

Max

mIII units are ruggedly built to

withstand hard use, and their gasketed

case, crystal and stem assemblies resist

encroachment by most fluids. However,

Max

mIII Indicators, Indicating Units and

Digital Transducers should never be

immersed. Regularly inspect all seals and

spindle boots to guard against fluid

penetration.

Digital Output Models:

To prevent contaminants from entering the

6 or 10-pin digital output connectors, the

dust cap should always be firmly in place

whenever an output cable is not connected.

Digital Transducers:

Any Max

mIII Indicating Unit can be used

with any Max

mIII Digital Transducer.

Make sure the transducer connector is

properly aligned with the indicator connector

before connecting them. Max

mIII

Indicating Units may not be used with

Max

mand Max

mPlus style remote

transducers. Max

mIII Digital

Transducers must be used with an adaptor

cable to connect to Max

mand Max

m

Plus Indicating Units.

(See Section 7.0 for adaptor cable part

numbers.) To disconnect the Digital

Transducer, pull the connector straight out;

do not twist or unscrew the connector. Also,

do not severely bend, twist or strain the

transducer cable.

2.0 PRODUCT FEATURES

2.1 Max

µµ

m



III Features

Switchable Inch / Metric Units

Allows the indicator to display in “in” units or

“mm” units. Selectable in the Setup Mode.

Tolerance Limits

Allows the selection of left and right

tolerance limits within the analog scale

displayed.

Range Signal

There are two conditions that occur when

the readings are over-range. The Off-Scale

condition occurs when the fan display

exceeds the analog scale and is indicated

by a flashing segment at the most left or

right segment location. The Over-Range

condition occurs whenever the digital

reading is exceeded and is indicated by a

blank display that shows both the polarity

sign and the in/mm units icon. Unit is still

active and not to be confused with the

Sleep Mode condition.

Selectable Digital Resolution

There are two selections for digital

resolution with each Digital Range

selection. See below;

Digital Range Available Resolutions

±0.100inch / ±1.99mm 0.0005” or 0.0001” / 0.005mm or 0.001mm

±0.040inch / ±1.0mm 0.0005” or 0.0001” / 0.005mm or 0.001mm

±0.0199inch / ±0.199mm 0.00005” or 0.00002” / 0.001mm or 0.0005mm

Selectable Digital Range

The “Short Range” Max

mIII unit is

capable of selecting two digital ranges. The

“Short Range” model can select between

±0.040 and ±0.199in (±1.00 and ±0.199mm)

ranges. The “Long Range” model has one

range of ±0.100in (±1.99mm) only.

Selectable Analog Magnification

Each Max

mIII unit is capable of

selecting between two minimum analog

graduation values. An inch/metric overlay

can be used for traditional analog display

preference. The “Long Range” model can

select between 0.001 and 0.0005in (0.01

and 0.005mm) resolutions. The “Short

Range” model can select between 0.001

and 0.0005in (0.01 and 0.005mm)

resolutions for the ±0.040in/±1.0mm range

and between 0.0005 and 0.0001in (0.005

and 0.001mm) resolutions for the

±0.0199in/±0.199mm range

Sleep Mode

The Max

mIII unit is designed with an

auto power down feature to conserve

battery life. If it senses approximately 10

minutes of inactivity (i.e. no spindle

movement, no buttons pushed, no digimatic

data output request), the unit will go into a

“Sleep” state. Display shows only a “+” or “-“

sign depending on measuring direction

selected in setup. Unit is inactive.

(Option) The sleep mode may be disabled

as a factory option when requested at time

of order. However, when using battery

power the life of the battery will be reduced.

This option is typically used with the

Remote External Power option, which

bypasses battery operation.

Transducer Range

Max

mIII Remote Indicating Units auto-

sense the type of Digital Transducer

plugged into it. There are two types of

Digital Transducers that are auto-sensed;

“Short Range” versions, which have a

±0.040in/±1.0mm measuring range and

“Long Range” versions, which have a

±0.100in/±1.99mm measuring range.

Digital Output

Each Max

mIII unit is capable of

selecting between three choices of data

output format; the Standard Max

moutput

format, the Max

mSerial output format,

and a digimatic output format.

Digital Calibration

The Max

mIII indicator can be calibrated

via pushbutton sequencing for accurate

performance.

Low Battery Signal

The text “Bat” is displayed on the digital

display signifying that a battery change is

necessary which helps avoid collection of

bad data. It initially flashes as a warning

then under continuous use eventually

remains on so that no readings will be

displayed.

Calibration Lockout (Option)

Allows the entry into the calibration mode

via an access key (Order No. 2240545 – 6

pin, Order No. 2240547 –10 pin) when

plugged into the data output port.

Calibration is inaccessible without this

Access Key. Specific models only.

Setup Lockout (Option)

Allows the entry into the setup mode via an

access key (Order No. 2240545 – 6 pin,

Order No. 2240547 –10 pin) when plugged

into the data output port. Setup mode is

inaccessible without this Access Key.

Specific models only.

Remote External Power (Option)

Allows use of remote power from an

external regulated power supply or data

collector via the data output port. When

remotely powered, battery is bypassed and

it is not used unless remote source is

inactive. Available on models that have a

data output port only. Never use an external

power supply on models that do not have

this special option feature.

Ratio Model (Option)

There are two ratios available for the

Max

mIII indicator. All standard models

come with a 1:1 ratio meaning 0.010inch

movement of the spindle results in

0.010inch reading on the indicators digital

display. Some applications require a 4:5

ratio. Max

mIII models ordered with this

4:5 ratio will read 0.008inch on the

indicators digital display when the spindle is

moved 0.010inch in linear travel. There are

no other ratios available on this indicator.

This is a factory set option.

CAUTION

Do NOT continuously toggle external

power source on and off as this can

cause damage to the digital indicator

and the remote power source.

Do NOT remove or install the external

power source cable while the

external source in on.

2.2 Controls – Standard Mode

Makes use of 6 push buttons (mode, left

limit, left display index, right display index,

right limit, autozero) for selections in two

Operating Modes (Standard and Enhanced)

and separately for entering the Setup Mode

and Calibration Mode. Buttons are only

active when a reading is on the display.

True Spindle Position (1)

Enters unit into its TSP mode to show the

actual position of the spindle in the

Indicator’s measuring range.

Left Tolerance Limit (2)

To set the left arrow at desired limit.

Display Switches (3)

To index the digital readout and analog

display clockwise (right-handed switch) or

counterclockwise (left-hand switch). The

display switches will function only when the

Indicator or Indicating Unit is in the “Auto-

Zero” (Gaging) mode.

Right Tolerance Limit (4)

To set the right arrow at desired limit.

Auto Zero (5)

To electronically set both the analog display

and digital readout to zero.

2.3 Controls – Enhanced Mode

Mode (1)

To show the real time static measurement

of the spindle in the indicator’s measuring

range while in Enhanced Mode. (Sec. 4.2)

When the mode button is used to activate

the enhanced function the indicator’s analog

display changes to the alternate mode, i.e.

a normal “Fan” display changes to a “Single

Element” display, and dynamic button

functions become active.

retention function. Displays the lowest or

most negative measurement seen by the

indicated movement.
