Selects the parameter setup mode.
When pressed during memory value call, returns to the
measurement mode.
Memorizes up to 20 measurement values present when
pressed.
Changes the peak-hold mode (MAX, MIN and normal) in
order.

Establishes the current setting condition and then moves
to the next setting.
④When 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.
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.
①Setting clearance of all memory values (Memory →

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.
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.

1. Memorizing Measurement Values
①To memorize the current measurement value, press the
MEMORY & →switch during measurement.
②When the measurement value is memorized, the
numerical value in the SUB display is incremented.
Therefore, the number00in the SUB display indicates
that there is no measurement value memorized.
③Up to 20 measurement values can be memorized.When
the number of the memory values reaches 20, no more
values can be memorized.
When you press the MEMORY & →switch at this time,
FULis displayed.
00 01 20 FUL
MEMORY
④Since memory values are stored in non-volatile memory,
they are retained even if you turn the power OFF.
2. Recalling Memory Values
①Memory values can be recalled by pressing the RECALL &
↑switch in the measurement mode.
The memory No.is displayed asmXX(for example, m05)
in the SUB display.
②Memory values are recalled from the latest memory No.
and then in order of the memory No., m01, m02, m03, and
so on.
③If there are three memory values, the value of memory No.
m03 is displayed first. Then, the SUB display displays m04
and the MAIN display displays −−−−−indicating
that there is no measurement value memorized.Therefore,
if there is no memory value,−−−−−is displayed at
m01.

④To return to the measurement mode, press the MENU switch.
The numerical value in the SUB display changes toXX
which indicates the number of values memorized (without
leadingm).

Check Point
①Are batteries set ?
②Are the batteries set at correct polarity ?
③Are batteries consumed ?
④ When using the AC adapter, is the dedi-
cated AC adapter connected to an outlet and
the DC input connector of the main unit ?
①Is the rotational speed slightly high ?
②Is the rotational speed slightly low ?
③Has measurement error occurred ?
Countermeasure
①Set batteries.
②Put the batteries at thecorrect polarity.
③Replace all batteries with new ones.
④Plug the dedicated AC adapter to an outlet and then
connect the DC plug to the DC input connector of
the main unit.
①When the gain for the sensor amplifier is Hi, selec-
tion may not be appropriate. Set the gain for the
sensor amplifier to the Lo level.
②When the gain for the sensor amplifier is Lo, selec-
tion may not be appropriate. Set the gain for the
sensor amplifier to the Hi level.
③The sensitivity may be higher than necessary. Re-
adjust it using the trigger level adjustment knob. (Re-
fer to Basic Operations/Before Use/2. Measurement/
(7) Setting the trigger level adjustment knob.)
Measurement Operations
1. Analog Output
【 When REVO is selected】
・The analog voltage output of the value set in the
setup mode as the analog output “F. S .”(full scale)
setting is output from the analog output connector.
・The analog output becomes 1V when the value of
the MAIN display agrees with the full-scale setting.
The minimum load resistance of the analog output
is 100k Ω.
Outputs
1. ERROR Display
If the error alarm mark lights up, one of the
following error has occurred.
①If the input frequency exceeds the upper-limit
frequency 66.67Hz, an over-frequency error occurs.
* Although the display value is averaged, the mark
lights up if the result of single measurement exceeds
the upper-limit frequency.
②If the rotational speed exceeds the specified range
a) If 8000 r/min is exceeded
b) If 133.33 r/s is exceeded
2. LOW Display
If the low alarm mark lights up, the battery has
been consumed and the low battery condition occurred.
・This mark lights up if the battery voltage drops to 4.5V
or less.
・If this mark lights up, immediately replace the four
batteries with new ones.
Using the consumed batteries may disable measure-
ment.
・If the batteries are further consumed under this con-
dition, measurement is disabled and the MAIN dis-
play displays −−−−−.
・If the battery voltage drops to about 4.5V or less, the
back light becomes dark (with no problem).
LOW display ERROR display
If you perceive any abnormal condition, first check the following points. If the instrument does not operate correctly
after check, contact your dealer (Ono Sokki agency) or Ono Sokki sales office nearby.

【When SIG is selected】
・The shaped waveform of the sensor signal (signal before
pulse waveform conversion) is output.
2. Pulse Output
・A pulse waveform shaped according to the detected
rotational signal is output from this connector.
・As for the output level, the Hi level is 4.5 to 5V and the
Lo level 0 to 0.5V. The minimum load resistance is
100k Ω.
3. Clearing All Memory Values
①To clear all memory values, selectCLrfor setup item

②When the memory values are cleared, the numerical value
in the SUB display becomes00.
Note: When you perform the memory clear operation
(all clear), the memory values are all cleared.
When there is a peak-hold value, it is also
cleared at the same time.
* If the problem cannot be solved with Troubleshooting, perform the following operation to restore all the settings to the
initial conditions (settings at the time of shipment).
While pressing the RECALL& ↑switch and MENU switch, turn the power ON. The GE-1400 returns to the initial
condition. However, memory values are retained (not cleared).
