6. Tests are being rejected because the test results indicate a rate increase >+0.4 gph.
Static Leak Test
If after troubleshooting the Periodic Leak Test Fail Alarm an equipment problem has not been identified, perform a
static leak test. Be sure that the product pump cannot come on during the test and that the level in the tank is
within the normal operating range (i.e., the results of the static test may not be meaningful if the tank is nearly
empty). If the static test verifies the CSLD result follow the procedures as established by the site owner. If the
static test passes, contact Technical Support for assistance.
When to Manually Clear the CSLD Rate Table
You should manually clear the CSLD Rate Table if data, known to be inaccurate, had been stored in the table and
the source of the inaccurate data was subsequently removed (e.g., after making tank plumbing repairs).
The CSLD Rate Table can be cleared by touching the Clear Table button on the CSLD Rate Table tab screen, or
via the RS-232 command shown below.
IMPORTANT! DO NOT CLEAR THE CSLD RATE TABLE UNLESS IT IS ABSOLUTELY NECESSARY.
