■ WIRING
• Do not install cables (power supply, input and output) close
to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises
are present. Do not install them in the same duct.

CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the described specifications shown below.

ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
■ HOW TO CALIBRATE THE OUTPUT SIGNAL
Connect a signal generator to the input terminal and a
frequency counter to the output terminal.
• Low-end Cutout Adjustment
1) Apply the desired input to be eliminated.
2) Turn the Low-end Cutout Adj. clockwise until the Cutout
LED is turned on.
3) Turn it slowly counterclockwise to the exact position
where the Cutout LED is still on but will be turned off if
it turned further counterclockwise.

Range Selector
• Output Range Adjustment (coarse range)
1) Select an appropriate coarse range in the table to the
right, and set the front accessed Range Selector.
• Zero/Span Adjustments
1) First nullify Low-end Cutout Adj. to 0%.
2) ZERO (fine range): Apply 5% input and adjust output to
5%.
2) SPAN (fine range): Apply full-scale (100%) input and
adjust output to 100%.
3) Check ZERO adjustment again with 5% input.
4) When ZERO value is changed, repeat the above procedure
1) – 3).
Remark: The output frequency is precisely doubled by turning Range Selector by 1 division to the counterclockwise
direction. In order to quickly make low frequency range
adjustments, conduct fine adjustment first with a higher
coarse range, and then change coarse range to the actual one.

MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 5%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accuracy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the "ADJUSTMENT PROCEDURE" explained earlier.
LIGHTNING SURGE PROTECTION
In order to protect the unit from lightning surges entering
through signal and power supply cables, use of appropriate
lightning surge protectors are recommended. Please contact
M-System.
