Instruction manual

5.5. Retrieving data from the logger

Use the program PC208 to retrieve all the ‘uncollected’ data from the data logger.

5.6. Operation of the logger program - C10-HP3.DLD

Here we describe a number of program changes and system tests that you may want to do.

We also describe some 'normal' program behaviour that may be expected during the

course of a measurement period. Note: After you have finished playing with the logger,

ALWAYS press *0 to recompile any changes, or to continue by leaving the logger in the

'LOG1' mode.

5.6.1. To change the interval between heat pulses (alter Inst-1)

enter *1 1 A A A x A *0 where x = interval in minutes

The default time is 30 minutes

5.6.2. To fire a test heat-pulse

enter *6 A D 1 (the lights should go on, and the program will run)

enter *6 A D 6 for an early exit of program

enter *0 to continue

5.6.3. To check if the system is working properly (generally a good idea!)

fire a test heat pulse (see 5.6.2)

check the initial voltages (+/- 20 mV is OK, -9999 is stuffed)

i.e. enter *6 x A where x = 41..56

check the present voltages (+/- 100 mV is OK, -9999 is stuffed)

i.e. enter *6 x A where x = 21..36

enter *0 to continue

Note. Readings are in mV so anything in the range +/- 200 is OK.

5.6.4. To examine

data (stored in locations 1..16)

enter *6 x A where x is the location.

loc. 1 = tz1-1 (outer) .... loc. 4 = tz1-4 (inner)

loc. 5 = tz2-1 (outer) .... loc. 8 = tz2-4 (inner)

loc. 9 = tz3-1 (outer) .... loc.12 = tz3-4 (inner)

loc. 13 = tz4-1 (outer) .... loc.16 = tz4-4 (inner)

enter *0 to continue
