Sampler Troubleshooting

6 Symptom

7 Probable Cause & Remedy

“Check Zeroing Bypass” message

appears at bottom of display.

The ESC key was pressed during startup, thus bypassing the normal sensor

zeroing process. Although the instrument will operate under this

condition, no leak rate tests should be made because of the potential

inaccuracy of the sensor channels.

“Check Background Greater Than

Leak” message appears at bottom

of display.

The measured background gas level is greater than the measured leak gas

concentration. Make sure the background gas sample hose is not

positioned too close the leak source.

“Low Battery” message appears

at bottom of display.

Battery voltage is below 4.0 volts. Recharge battery pack per Section 4.2.

7.1 Error Codes in Saved Test Records

When saved test records are sent to a personal computer and later viewed in a

spreadsheet program (refer to Section 2.16 Importing Saved Data into a Spreadsheet),

Field 18 “Error Codes” in the saved records contains letter-codes that identify problems

that have occurred during that particular test. Refer to Table 5-2 for a listing and

description of these codes.

TABLE 5-2. FIELD 18 ERROR CODES

Error

Code

Description

A Background gas sample pump blocked.

B Leak gas sample pump blocked.

C The background gas sensor needs calibrated at 2.5% and/or 100% CH

D The leak gas sensor needs calibrated at 2.5% and/or 100% CH

E The instrument failed to zero the background gas sensor during start up.

F The instrument failed to zero the leak gas sensor during startup.

G The user pressed the ESC key during start up before the sensors had a chance to completely zero.

H The leak rate measurement #1 – #2 calculation failed.

I The measured background gas level was greater than the measured leak source gas level. (This is an

indication of improper equipment setup.)
