Start up
 Power up intrinsically safe circuit. Green LED on Hydrosteel 7000 should light to show correct power
is available to the unit. (the measurement cycle will start automatically)
 Power up 4-20 mA circuit. 4mA should register on each circuit.
 If any discrepancy from the above is encountered see fault finding and diagnostics in the
Maintenance section
Operation test
Basic test
1. Allow the Hydrosteel to complete one measurement cycle (10+ minutes from switch on). If the green
LED is continuously lit, the power is confirmed as correct. If the Green LED starts to flash then the power
dropped below 15 V (browned-out) during the measurement cycle and it has restarted. See fault finding
and diagnostics in the Maintenance section.
2. If the red LED illuminates, a fault has occurred during the measurement cycle. See fault finding and
diagnostics in Maintenance section.
3. Perform a data download. Check that no diagnostics have failed during the first measurement cycle. If
any diagnostics have failed again, please refer fault finding and Diagnostics in the Maintenance section.
4. The flux reading can be correlated by using a Hydrosteel 6000 close to the Hydrosteel 7000 probe point.
Record a Flux reading on the hand over document.
5. The pipe temperature can be correlated by measuring the temperature at the probe steel surface or by
connecting the Thermocouple to a hand held thermocouple thermometer. Record the first thermocouple
reading on the hand over document.
Test if Hydrosteel function test is available
1. Disconnect the flux (AT-S) probe and connect hydrogen flood leak sample conduit.
2. Allow the Hydrosteel to complete one measurement cycle (10+ minutes from switch on).
3. Perform a data download.
4. The flux reading should be between 280 pl/cm
2
/s and 380 pl/cm
2
/s. Record the flux reading on the hand
over document.
5. The pipe temperature can be correlated by measuring the temperature at the probe steel surface or by
connecting the thermocouple to a hand held thermocouple thermometer. Record the first thermocouple
reading on the hand over document.
4-20 mA test
1. Both 4-20 mA outputs should be 4mA from unit switch-on of the 4-20 mA power supplies for each output.
After the first measurement cycle is complete the 4-20 mA output will be up dated to reflect the current
reading.
2. The 4-20 mA output after the first measurement cycle can be ascertained by performing a data download
and using the flux and pipe temperature readings to calculate the 4-20 mA outputs. See the table below:
Detector Range Resolution Accuracy
4 mA 20 mA 10 mA
Flux (AT-F probe) 0 pl/cm 2 /s 2400 pl/cm 2 /s* 1 pl/cm 2 /s  10 % at cal. Value
Pipe temp -40  C 500  C 2  C  2  C at cal value
3. Note: Flux 4-20 mA output range may be changed see Hydrsoteel setup section.
4. Check the initial 4 mA reading and any subsequent readings have been correctly measured by the 4-20
mA receivers.
5. Program the correct units and range for each output into the “data collection system”. See the table
above.
