1. Preliminary Check

1. Identify the analyzer PCB detector order using the reference diagram.
2. Typically:
   • Detector 1 = Circulation sampling pump.
   • Detector 2 = Analyzing sampling pump.
   • Pump Room Part 3 Flow = Typically assigned to Detector 9, but confirm Refer to analyzer PCB or diagram.
3. Verify the Gas Sampling System version by:
   • Turning the display power OFF and ON or performing a Lamp Test.

2. Entering Calibration Mode

For HGS-100C Version 6.05 and Earlier

1. Press F5 (CFG) → Enter Password: "1234".
2. Select Detector Calibration.
3. Input the Detector number (Refer to approval drawing or analyzer PCB).

For HGS-100C Version 6.05 and Later

1. Press F4 (UTIL) → F1 (DT.MOD) → F2 (DT.CAL).
2. Enter Password: 1234.
3. Input the Detector number (Refer to approval drawing or analyzer PCB).

⚠️ Note:

• Detector No.1 = Sampling Pump 1 (Circulation).
• Detector No.2 = Sampling Pump 2 (Analyzing).

3. Calibration Procedure

Step 1: Select CURVE Mode

1. Enter Calibration Mode and select CURVE.
2. Verify the overall current (mA) values.

Step 2: Adjust 3-Way Valve

• For Circulation Flow Setting (Flow 1):
  • Turn the 3-Way Valve right to the Calibration side.
• For Analyzing Flow Setting (Flow 2):
  • Turn the 3-Way Valve left to the Sampling side.

⚠️ Caution:

• The valve should remain in the Sampling position under normal operation.

4. Flow Setting Process

1. Zero Flow Adjustment:

   • Close the Calibration Flow Meter Valve completely.
   • Wait 10 seconds to stabilize the flow meter ball and current values.
   • Press Set and Enter to save the current (mA) value.

1. Incremental Flow Adjustment:

   • Move the cursor to the next line and press Enter.
   • Adjust the Flow Meter Knob to 1 L/min.
   • Press Set and Enter to save the current (mA) value.
   • Increase the flow meter by 1 L/min to set current values from Flow No.2 to No.9.

1. Maximum Flow Adjustment:

   • Open the Flow Meter Knob fully and set Calibration 10.
   • Confirm that the knob is fully opened before saving.

5. Final Confirmation

1. Set the Calibration Flow Meter Knob to 300 L/h, referring to the display unit.
2. Ensure all flow settings match the reference diagram.
3. Repeat the Flow Setting for the Pressure Transmitter using the same procedure.

Important Notes:

⚠️ Caution: Ensure correct detector assignments before proceeding with calibration.
⚠️ Warning: The reference current values in the images are placeholders and may vary based on sampling pump performance.

⚠️ Warning:The current value of the Flow Setting should increase sequentially.
