Warning
•Do not use this unit with voltages other than the specified supply voltage as this may
result in fire or electric shock.
• Do not handle the I/O connector with wet hands as this may result in electric shock.
• Do not open the cover of the counter unit to disassemble or modify the unit, as this
may result in burns or injury. These actions may also damage the internal circuitry.
• This device operates with DC power supply. Absolutely do not connect an AC power
supply to the I/O connector as this may result in fire or electrical shock. Doing so may
also damage the internal circuitry.
Caution
• The unit does not have an explosion-proof structure. Therefore, do not use the unit in
an atmosphere charged with inflammable gases as this may result in fire.
•Be sure to turn off the power before connecting or disconnecting power and signal

1-1. General precautions
When using Magnescale Co., Ltd. products, observe the
following general precautions along with those given
specifically in this manual to ensure proper use of the
products.
• Before and during operations, be sure to check that our
products function properly.
• Provide adequate safety measures to prevent damage in
case our products should develop a malfunction.
• Use outside indicated specifications or purposes and
modification of our products will void any warranty of the
functions and performance as specified for our products.
• When using our products in combination with other
equipment, the functions and performance as noted in
this manual may not be attained, depending upon the
operating environmental conditions. Make a thorough
study of the compatibility in advance.
• Design and specifications are subject to change without
notice.
1. Note to users
1-2. Handling instructions
• Do not open the cover of this device or put your hand
inside. Otherwise the internal circuit may be broken by
static electricity.
• To prevent malfunctions caused by static electricity,
always turn off the power when touching other parts than
the key switches.
• Do not route the connecting cable through the same duct
as the machine power line.
• To prevent misoperation of surrounding equipment due
to noise emitted from this counter unit and vice versa,
connect the power cable in a twisted manner when
supplying DC power.
• When providing DC power, be sure to use within the
specified voltage range.
• Absolutely do not connect an AC power supply to the I/O
connector. Doing so may damage the internal circuits.
• Do not use connection prohibited I/O connector pins as
relay pins.
• When connecting the BCD connector, be sure to wire the
connector correctly.
Failure to do so may damage the internal circuits.

LT10A / LT11A Series
1-4. Instructions for connecting to
the measuring unit
• The LT10A/LT11A is a counter unit designed for the DT
series measuring unit.
• When the LT10A/LT11A is connected to a DT series and
turned on, the digits corresponding to the channel
connected may flash. This shows that initialization is
required to calibrate the new pairing of both device and
unit. Here you should move the measuring unit at least
1 mm, as shown in the figure, and then press the reset
key on the LT10A/LT11A corresponding to the channel.
The device will now return to its normal measuring state.
Note
Once this procedure has been carried out the digits will not
flash while the device is connected to that measuring unit,
even if the power is turned off.
• Place the counter unit more than 0.5 m (20") away from a
high voltage source, large current source, large power
relay, etc.
• For installation of the counter unit, avoid a location
exposed to chips, cutting oil, or machine oil. If
unavoidable, take adequate countermeasures.
• Do not put a vinyl cover directly over the counter unit or
put it in a closed container.
• The ambient temperature should be in the range of 0 °C
to 40 °C (32 °F to 104 ° F). Avoid exposure to direct
sunlight, hot air currents, or heated air.
1-3. Cautions on operation
Carry out the key operations or I/O (BCD, etc.) connections
and operations in line with the explanations given in the
appropriate sections. Failure to correctly operate this
device may result in a malfunction.

With the 2 channel models the upper and lower
selections of the front panel’s main display correspond
to the BCD OUT. A/BCD OUT. B. So if “A+B” is
selected the output is to BCD OUT. A.
The following operations are possible when BCD
input/output terminal is used.
Input : Comparator value selection (4 settings),
measuring mode (current value, maximum value,
minimum value, peak-to-peak values) selection
Output: 5 digits
Outputs one of the current, maximum,

4-3-4. Peak-hold function
• Stores the maximum, minimum, and peak-to-peak
(maximum–minimum) values of the measured values.
• The above mentioned measuring mode is set using the
keys on the front panel.
• The device starts storing values either when a start signal
is supplied to the start/latch pins (channel A: pin w,
channel B: pin r) of the lower 7-pin I/O connector
(common) (See “6. I/O connector”.) or when the reset key
has been pressed.
4-3-3. Result evaluation
• Go/No Go test is carried out by comparing data from the
current measuring mode (current value, maximum value,
minimum value, or peak-to-peak value) to the comparator
upper and lower limits.
• This result is displayed on the front panel and output from
the I/O connector (See “6. I/O connector”.).

1. Setting the display
(2 channel models)
One of the following may be
chosen:
When the upper display A+B is
selected, the lower display only
shows the current value of the
selected channel and no
operation can be made on the
lower display.
2. Setting the display resolution or direction
(channel A)

• With the measuring unit’s
spindle pushed in:
+: positive direction
–: negative direction
∗ When set to inches, values are chosen from 0.0002,
0.0005, –0.0002, and –0.0005.
Note
With the LT10A series, 0.001 mm and –0.001 mm (0.0001"

Setting this terminal
to “L” (ON) sets the
peak-hold value to
the current value and
restarts the storing
procedure.
: Latch function
When using the current value measuring
mode, setting this terminal to “L” (ON) stores
the output and display of the Go/No Go
comparison at that point in time.
Note
When the latch is ON, display and Go/No Go
output storage by the DRQ input for the BCD
model and RS-TRG input for the RS-232C
model is invalidated.
Initial settings are now complete for the standard model.
Pressing

• With the measuring unit’s spindle pushed in:
+: positive direction
–: negative direction
• When displaying A+B:
If you set the direction of A to “–” the data displayed is
the calculation “–A+B”.
The same can be done with B.
Note
• With the LT10A series, 0.001 mm and –0.001 mm
(0.0001" and –0.0001") are not avaible.
