OUT Outlet connected to the reference gas chamber. The exhaust from the outlet must be emitted into the fresh air at atmospheric pressure. (12) GAS OUT Outlet for measuring gas sucked from the GAS IN. (13) DC6V 6VDC Interface for the specific AC adaptor. (14) REC. A jack for 0-1VDC output.
2. MEASURING MODE (POWER KEY) 2-1. Basic Display for Measuring Mode and Explanation Display Contents Status Gas Name and Base Gas Standard measuring mode. CAUTION CHECK AIR CAL. CAUTION ABNORMAL TEMP. CAUTION LOW BATT. CAUTION LOW CONTRASUT CAUTION LOW BRIGHTNESS Zero drifting might be occurring. Let the monitor sample fresh air and perform AIR CAL. Internal thermistor detects an abnormal temperature. Battery voltage is low. Replace the batteries. The interferometer sensor is getting contaminated.
2-2. Procedures from Power ON to Measurement 1) The power is turned on by pressing the POWER key until the buzzer beeps. The initial display (self-diagnostic display) will show up as well. A display that confirms the setting will then appear. After two seconds, it will proceed to the basic display of measuring mode. Self-Diagnostic Display Confirmation Display Caution This instrument does not indicate a correct reading if the measuring gas and base gas are not selected properly.
completed, press the PUMP key and let the sample gas draw into the instrument. The color of the display will reverse while the pump is operating. *Note that the indication on display under pump operation is not measuring result. 6) After the indication on the reverse display becomes stable, the pump will stop the operation and read out the indication as a measuring result at this pump operation stop. At this pump operation, stop under the gas flow ceasing condition. This is the measuring result.
2-3. Saving Data 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. 2-4.
2-5. ERROR Message Display If the problem proceeds to affect the measurement, an ERROR message (as shown to the right) will appear. 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.
2-6. AIR CAL CAUTION If the temperature inside of the sensor has changed over ±10ºC from the last time the AIR CAL was performed, [CAUTION/CHECK AIR CAL] will be displayed in order to prevent zero drifting. [Measuring Gas/Base Gas] and [AIR CAL] are displayed consecutively. If the [CAUTION/CHECK AIR CAL] is displayed, perform the AIR CAL based on the procedure below: AIR CAL Procedure 1. Press the PUMP key and let it sample fresh air. 2.
Caution The pressure in the Gas Chamber changes from the atmospheric pressure while sampling the gas. As a result, the indication will not be accurate (note that if an instant pressure change occurs in the Gas Chamber or the reference Chamber, the indication might also go wrong.) If these symptoms occur, perform the AIR CAL right away. Also, be sure to note the following points: > > > > Do not plug the GAS IN or GAS OUT while the gas is feeding.
An example of measurement when the pressure of the sampling point is higher than that of the atmospheric pressure: Make an inlet (a) as drawn below. Open and shut the stop valve to feed the gas to the instrument, rather than turning the pump on and off. Read the indication when the valve is shut off and the gas flow completely stops. Flow rate at inlet (a) should be 300 to 400mL. GAS OUT should be at the atmospheric pressure and the REF. OUT should face fresh air.
3. SETTING MODE (ENTER + POWER) The SETTING MODE is for “Change the Measuring Gas,” “Adjusting the time,” and “Confirming the Saved Data.” Enter the SETTING MODE by pressing the POWER key while the ENTER key is also being pressed. Once you enter the mode, the display shown right will appear. Move the cursor (black bar) with the keys and select the item you wish to set up. Go into the item by [ENTER key].
3-2. Adjusting the Time (SET DATE/TME) The initial position of the cursor is on YEAR. Change this with the keys and fix the setting with the ENTER key. The cursor then moves to DAY. Select the DAY, MONTH, HOUR and MINUTE by the same procedures as YEAR. HOUR is displayed through a 24-hour clock. 3-3. Confirming the Saved Data (VIEW SAVED DATA) On the first line, the data number is shown. On the second and third lines, the saved data and time are displayed.
4. MAINTENANCE 4-1. Replacing the Batteries Warning > All the C-size Alkaline batteries used in the instrument should be the same kind. > Replace all four batteries at the same time. 1) 2) 3) 4) Confirm that the power is off. Remove instrument out of carrying case. Remove the old batteries and replace them with the new ones in the correct direction. Once you have replaced the batteries, place the battery cover on the bottom. 4-2.

10. MEASURING PRINCIPLE The Reflection ratio of gas mixture is determined by the kinds of composing gases as well as the mixture ratio. As long as the kinds of composing gases are known, the mixture ratio (concentration) can be determined by measuring the reflection ratio. The optic interferometer applied in the RK60000 displays “Interference Stripes” on the CCD. The Interference Stripes move proportional to the reflection ratio.

Gas Purity Indicator for SF6 (RK60000-SF6) Simple Instructional Manual SECTION 1. POWER ON 1-1. Make sure that the change over cock (measuring gas/air) is turned sideways. 1-2. Press the power button on the Model RK60000 until beeping.
SECTION 2. ZERO ADJUSTMENT 2-1. Adjust the flow rate to be 0.2±0.04 L/min at flow meter “B” (located right on the panel). 2-2. Verify that the indication value has been stable and press the AIR CAL button until it starts to beep.
SECTION 3. PREPARATIONS FOR GAS SAMPLING AND MEASURING 3-1. Connect the sampling tube to the gas inlet “GAS IN” on the panel and apply the sampling gas (SFG) from the sampling point. The sampling gas pressure should then be less than 0.7 MPa. 3-2. Make sure that the pressure regulator on the panel is set 0.1±0.02MPa. Regulator adjustment must be done at step 4. SECTION 4. START MEASURING 4-1.Turn the change over cock (measuring gas/air) vertical. The unit will begin to measure.
The higher that the flow rate of meter “A” is set, the sooner its indication will be stable. Also, since the instrument has air in the internal piping, regulator, or sampling tube, we recommend adjusting the flow monitor “A” so that it is more than 0.8 L/min every first turn when measuring. SECTION 5. OTHER OPERATION 5-1. Incase of checking zero or suspending measuring, turn the change over cock (measuring gas/air) sideways. 5-2. It is enough for further measuring to set flow meter “A” 0.
