Functions and Operations
1. Power Supply Switch
① When you slide the power switch upward, the power of the
main unit turns ON.
② When you turn ON the power, the software version is
displayed in the MAIN display and the product code
"GE1" of the main unit in the SUB display. Then, the
measurement mode is entered.
③ For each parameter, the condition of previous
measurement is backed up.
Measurement Mode
Power switch Ends the measurement mode and then turns OFF the power.
RECALL & Recalls the memory value in sequence.
↑ switch
Selects the parameter setup mode.
MENU switch
When pressed during memory value call, returns to the
measurement mode.
Memorizes up to 20 measurement values present when
MEMORY &
pressed.
→ switch
Changes the peak-hold mode (MAX, MIN and normal) in
MODE &
order.
NEXT switch
3. Setup Mode
When you press the MENU switch in the measurement mode, the parameter setup mode is selected.
Then, set parameters using the RECALL & ↑ and MEMORY & → switches. Apply parameters and select items using
the MODE & NEXT switch.
The operation flow in the parameter setup mode is shown below.
Measurement mode

④ When you perform measurement for the first time, set
each parameter first.
2. Function of Each Switch
When you turn ON the power, each switch has a different
function between the measurement mode and the pa-
rameter setup mode
The function of each switch in each mode is shown be-
low.
Parameter Setup Mode
Cancels the current setting and then turns OFF the power.
Changes the selection of the current setting.
During numerical parameter setting, increments the
numerical value of the relevant digit.
When 9, returns to 0.
Establishes the current setting condition and then
change to the measurement mode.
During numerical parameter setting, moves the setting
cursor to the right. When it is at the least significant digit,
returns to the most significant digit.
Establishes the current setting condition and then moves
to the next setting.
MENU
End the parameter
setup mode.

① Setting clearance of all memory values (Memory →
mEm)
When you press the MODE & NEXT switch when "CLr"
is displayed in the MAIN display or press the MENU
switch to return to the measurement mode, the memory
values are all cleared.
Note: The setting of this function is not retained. When
you select this item, "SAuE" is initially selected.
SAuE Saves the memory values.
CLr Clears all the memory values.
Also for the following settings, when you press the
MODE & NEXT switch to move items or press the
MENU switch to return to the measurement mode, the
setting condition is established.
② Setting the lighting condition of the LCD back light (Light → LGT)
Turn the LCD back light ON or OFF
OFF Back light OFF
ON Back light ON
* Set to "OFF" at the time of shipment.
③ Setting the gain of the sensor amplifier (GAIN → GIN)
Set the gain for the sensor amplifier.
Hi Sets the gain for the sensor amplifier to
the Hi level.
Usually, measurement is performed
with the Hi level setup. However, if the
rotational speed is not stable (the
rotational speed becomes slightly high)
when, for example, disturbance noise
or signal of other cylinders is detected,
set the gain to the Lo level.
Lo Sets the gain for the sensor amplifier
to the Lo level.
If the rotational speed is not stable (the
rotational speed becomes slightly low)
when the Lo level is selected, the
amplitude of the sensor signal may be
small. Set the gain to the Hi level.
* Set to "Hi" at the time of shipment.
④ Setting the measurement unit (Unit → UNT)
Select the measurement unit.
r/min Rotational speed per minute
r/s Rotational speed per second
(Decimal point position 0.00)
* Set to "r/min" at the time of shipment.
⑤ Selecting the analog monitor output (Monitor → moN)
Select the signal to be output as an analog output.
rEuO Voltage output proportional to the
rotational speed
Sig Output for monitoring the sensor signal
Signal after waveform shaping
(before pulse conversion)
* Set to "rEuO" at the time of shipment.
⑥ Setting the analog output full-scale value (Full Scale → FS)
Set the count value corresponding to the full-scale
value (F.S. value: 1V) of the analog voltage output.
Setup range: 1 to 99999 (when 0 is set, 1 is set
automatically)
When 10000 r/min corresponds to 1V, set 10000.
* Set to "99999" at the time of shipment.
⑦ Setting analog output calibration (Calibration → CAL)
Output the calibration signal at 0V or 1V for the
analogue voltage output.
Note: The setting of this function is not retained. When
you select this item, "0u" is selected initially.
The selected analog output is enabled only
while the same item is selected.
0 V Output at 0V
1 V Output at 1V
