Fig 2: Charging station for eMultiCheck
1.1 Starting up
Before the device is used for the first time, it should be fully charged in order to ensure a maximum
battery life. To do this, just push the eMultiCheck into the charging station. An indexing system on both
parts ensures that it can only be pushed in the right way round. The first time, the charging time should
be at least one hour. The device is then fully operational.
To remove from the charging station, hold the station tight and pull out the eMultiCheck.

1.2 Switching on
The device can be switched on by pressing one of the two buttons on its front (button A or B, Fig. 4).
The drag moment of the drive is then automatically calibrated. During calibration, the drive turns for a
short time at a constant speed. This process takes place every time the device is switched on. It is
important to remember this when the device stays screwed into a component for more than 3
minutes.
Fig 4: eMultiCheck
1.3 Switching off
The device switches off automatically after about 3 minutes when none of the buttons are pressed.
1.4 Procedure of inspection for internal threads with gauges
Application of the GO screw plug gauge
The GO thread plug gauge checks the virtual size of the internal thread. This is effected by checking
the minimum limit of the pitch diameter, taking into account pitch errors, errors in the flank angles and
deviations of form, which produce an apparent reduction of the pitch diameter of the workpiece. In
addition it checks the minimum limit of the major diameter and also whether the length of the straight
flank is sufficent, i.e. that the rounding at the root of the profile does not encroach too far upon the
flank of the thread.
!!!!! This gauge does not check the minor diameter of the workpiece thread. !!!!
The GO thread plug gauge screwed by hand, without using excessive force, shall enter the whole
length of the workpiece thread. If entry is not possible, the workpiece thread does not comply with the
specification.
Important:
Before starting, the readout has to be zeroed by pressing the SET button on the Electronics. The
DigiMultiCheck is then ready for operation.
Principle:
The zero positon of the gauge is equivalent to the middle of
the truncation of the thread, 0,5xP. This means half of the
pitch between middle of truncation and end face.
(see illustration).

2Using the eMultiCheck
The eMultiCheck is operated with the two buttons on the front of the device. The blue button (button C)
at the side is used for adjustment.
2.1 Screwing in:
To begin the measuring process, press the black button (button B) on the front and the plug gauge
begins to turn slowly (phase 1).
The plug gauge is placed on the thread that needs checking. If a defined torque is exceeded, the
device assumes that the plug gauge is in the component (initial contact or thread found) and increases
the torque and the speed (phase 2).
During this phase of screwing in, if the plug gauge is blocked, it is turned back in the opposite direction
by 180°and phase 2 is started again.
After one more revolution the device accelerates again and the torque is adjusted to the set target
torque (phase 3).
When the thread depth is reached (the end) the device is switched off due to the set torque being
reached (phase 4).
In phase 4, the measured thread depth is stored in the memory and used as a reference for the next
measurement. This can be influenced with the settings (please also see the "Setting“ section).
The measured thread length can now be read off the display (the display must first be switched on by
pressing the button. Please note: the display and the motor/controls are independent of one another,
i.e. no data exchange takes place between these units).
2.1.1 Manual mode
Pressing and holding down the black button (button B) switches the device to manual mode. Here, the
device is switched over immediately to the fast speed and switched off again when the set torque is
reached.
2.1.2 Through-holes
With through-holes, when the plug gauge exits through the other side of the hole, the torque drops,
making the device switch off. This function is used for larger threads where the difference between idle
torque and load torque is large enough.
2.2 Second measurement:
In a second measurement, the sequence of phases 1-3 is the same as in the first measurement.
Before the last measured thread depth is reached, however, the speed is reduced, in order to prevent
contact at the end and to move carefully (gently) against the thread. This ideally reduces the load on
the component and the thread plug gauge.
If the thread is deeper, the speed is automatically increased again and is the same as in the normal
measuring sequence.
2.3 Screwing out:
The plug gauge is unscrewed from the component again by pressing the white button (button A) on
the front of the device. This is done by pressing the button briefly and the device stops automatically
when the plug gauge has turned back completely again. If the black button is pressed and held down,
the plug gauge turns until the button is released again. In this mode, the torque is not limited.
2.3.1 Manual mode
If the white button is pressed and held down, the device switches to manual mode. In this mode, the
device is set to the maximum torque until the button is released again.

3.3 Preset mode
Preselection of a reference value (preset)
The two reference values (REF I and REF II) can be preselected differently and up to a maximum
preset value of ± 2999.99 mm / ± 89.9995 IN.
1. Select active reference value (in reference mode).
2. Select preset mode (press and hold [mode] until the status display shows 'PRESET').
Entering the value you want to change
Press [mode] briefly one or more times to move the cursor under the number you want to change.
After the last number the cursor moves under the +/- sign again.
Changing a number
Press [set] briefly one or more times to increase the underlined number by one unit. Press and hold
the [set] button to move through the numbers automatically until the required value is reached.
Changing the preset +/- sign
Move the cursor under the sign and change the sign by pressing [set] briefly.
Confirming the preselected reference value (preset)
Press and hold the [mode] button until the 'PRESET' status display disappears.
Recommendations for use
For REF I, preselect the reference value 0.000 as a constant preset value, and use REF II for the
preselection of different reference values.
3.4 Connecting the serial interface:
To connect the serial cable (option) the cover has to be removed. The label of the connector must look
downwards to plug it in.
3.5 Special note:
- Contaminations of the device could affect the measuring process
- To clean a contaminated device please use a dry towel. If it is not sufficent please use a towel
with a neutral solvent. To prevent any damages don’t use volatile solvent, as it causes
damages on plastic parts.
- At regular intervals please lubricate the plug gauges with a resin free oil. It will prevent the
gauge from corrosion.
- Opening the device will leed to loose the warranty claim.

4Setting
Before changing to Setting mode you must change to the M8 thread plug gauge which is delivered as
standard (except for changing the depth mode). A gauge sleeve is not needed in this case!
Press and hold the blue button at the side (button C) for a while (approx. 3 seconds) to change to
Setting mode. This mode can be recognised by the movement pattern of the plug gauge (turning
forwards, backwards) and is the first level.
4.1 Setting level 1 Rotational direction/Torque
Change to this level by pressing the black button (Button B).
The plug gauge now executes a short pattern of movements and then turns slowly in one direction.
You can use this mode to set the rotational direction and torque. This is carried out by using the
adjusting block supplied. There are two levels of holes on this block. These holes only differ in depth
and are not used to calibrate the depth measurement but to select a data set.
To select a data set, three holes must now be tested. The first dictates the rotational direction (right or
left-hand rotation). The second and third holes adjust the required torque. This can be set at nine
different levels.

4.1.1 Pattern of movement
Different patterns of movement can occur during the setting process. These are characterised by:
(left-hand rotation)
1. One short turn 1st hole is the next hole
2. Two short turns 2nd hole is the next hole
3. Three short turns 3rd hole is the next hole
4. Alternating left/right-hand turns at short intervalsmeasuring error
In the event of a measuring error (4) the turning pattern for the next hole is displayed again.
4.1.2 Torques
In the relevant standard, there are no fixed torques determined for testing threads. The only
specification is "screw in with light manual force“. The table below shows the torques with
recommendations for a thread size. However, in the end there are many influences that make it
necessary to adapt the torque (material, tolerance range of the thread, etc.).
Please note: fluctuations in torque can occur due to temperatures and motor tolerances.

4.2 Setting level 2, Depth measurement
In the depth measurement, the aim is to move gently towards the end of the thread, as previously
described above. This is done by counting and saving the number of revolutions required for the
previous measurement. In this way, for the following measurement the speed is reduced one
revolution before the predicted end. This learning process is set to a fixed depth when this mode is
activated. Activating this mode again resets this value and makes the device switch over to normal
mode. There is not a display to indicate which mode is active, this can only be ascertained by
measuring different thread depths.
To enter depth measurement mode, press the white button (button A).
5ssembling the basic device / plug gauge
Fig 6: Assembly
The plug gauge is mounted in a specially pre-adjusted fitting. First the sleeve on the basic device must
be pulled back and then the plug gauge with fast-change connector can be pushed into the sleeve
(this must click into place with both surfaces). Releasing the sleeve locks the plug gauge in place.

5.1 Screwing in the gauge sleeve
The gauge sleeve is now pushed over the gauge and screwed in as far as it will go with manual force.
For thread sizes of more than M14, the gauge sleeve must be screwed in first and then the plug
gauge. The sleeve can be pulled back at the opening in the gauge sleeve.
The eMultiCheck is now ready for use.
