Introduction

*Note: Advice on Usage

Thank you for purchasing the Model RK60000. This instrument is a portable gas monitor to
measure “Helium in N2,” “CH4 in air,” and other gas concentration and calorie (valid only to the
measurement mentioned in the attached measuring gas specifications) intermittently.

This instruction manual is a guidebook on how to operate the Model RK60000. Both beginner
users and experienced users must read this manual and understand the contents thoroughly prior
to operation.

This instrument is to be used solely for the purposes mentioned in this manual and the attached
measuring gas specifications.

For your safety, the following marks have been included in this manual.

Danger

The liability or exposure to harm or injury.

Warning

If the instrument is not operated accordingly, it may serve as a serious hazard or health risk.

Caution

If the instrument is not operated accordingly, it may malfunction or serve as a serious hazard.

As the kinds of measurable gas and range vary depending on the type of RK60000, refer to the
attached measuring gas specification. For standard models, refer to the attached “each TYPE
measuring gas specification.”

If the [AIR] is selected as the base gas, the indication will show a zero when the AIR CAL key is
pressed. However, if the [N2] or other gases except [AIR] are selected as the base gas, the
indication will not show a zero, bur rather other values determined based on the combination of
the measuring gas and the base gas. This is caused by sampling the gas which is not on target (in
this case, the air.) Note that the instrument is not broken. Once it samples the target gas, it shows
a correct reading. Depending on the combination of the measuring gas and the base gas, the AIR
CAL value may be a negative value. For further information, refer to the measuring gas
specification.

Caution

RK60000 performs best when both the Gas Chamber and Reference Chamber are at the atmospheric
pressure (101.3 kPa.) While the measuring gas is being sampled, the pressure in the Gas Chamber
will become slightly different from the atmospheric pressure, and the analyzer will not show the correct

RK60000 measures the gas best when both the Gas Chamber and Reference Chamber are at

101.3 kPa. If precise measurement is required, perform the pressure correction by the following
method:

2-3. Saving Data

2-4. Initial Display (Self-Diagnostic Display)

Once the SAVE key is pressed, the buzzer will beep and the
display shown right will appear. The time, data, and the
measurement result are saved chronologically from No. 001
to No. 100. The saved data can be seen at “VIEW SAVED
DATA” in the SETTING MODE. Also, the saved data can be
deleted with “CLEAR SAVED DATA” in the SETTING MODE.

After starting with the MEASURING MODE by pressing the
POWER key, the self-diagnostic function will automatically
begin to work. If the result is normal, the display shown to
the right will appear.

If any problems occur, it will be indicated as shown in the
display at right. The display exemplifies a contamination of
the interferometer. If the problem becomes serious, the
display will not switch to the basic display , but instead the
ERROR message display.

2-5. ERROR Message Display

ERROR message and the meanings are as follows:

Contents of Display

The Meanings and Required Solutions

ERROR: LOW BATT.

Battery voltage is too low to perform the measurement. Replace the
batteries.

ERROR: CONTRAST

Contamination of the optic interferometer sensor is too severe to
perform the measurement. Replace the sensor or have it repaired.

ERROR : BRIGHTNESS

The brightness is too low to perform the measurement. Replace the
sensor or have it repaired.

ERROR: SETTING

The setup data saved in the setting mode has an error. Confirm the
setup data in the setting mode and set the data again.

ERROR: SYSTEM

A system error has occurred. Repair work is required.

ERROR: PUMP

There is a possibility that the pump is not working. Pump replacement
is required.

If the problem proceeds to affect the measurement,
an ERROR message (as shown to the right) will

appear.
