DIAGNOS – Enters the diagnostic function. Press the Up Arrow
Keypad button to toggle between the monitor’s two diagnostic screens.
Refer to
Working with the DIAGNOS Function (Page 21).
GASTYPE – Used to select of any one of 30 gas types plus one custom gas
for monitoring. Factory default is R-134a. Note that the factory can
program a custom gas type as specified on the sales order, or a custom gas
can programmed into the monitor at a later time using the CUST K1, K2,
K3 function. Use the Keypad to select the desired gas type, and then press
ENTER to save the selection and return to the previous screen.
Gases Available for Selection: R-11, R-12, R21, R-22, R-23, R-113, R-114, R-123, R-124,
R-134a, R-227, R-236FA, R-401a, R-402a, R-402b, R-404a, R-407a, R-407c, R-408a, R-409a,
R-410a, R-500, R-502, R-503, R-507, R-508b, H-1211, H-1301, H-2402, N-1230, CUSTOM
LEAKLVL – Sets the Leak Alarm level, adjustable from 1 to 300 ppm.
Factory default is 100 ppm. Note that the Leak Alarm level cannot be set
higher than either the Spill or Evacuate Alarm levels. Refer to Appendix
for recommended alarm settings for other gases. Use the Keypad to set
the desired Leak Alarm level, and then press ENTER to save that level
and return to the previous screen.
SPILLLVL – Sets the Spill Alarm level, adjustable from no lower than
the Leak Alarm level to a maximum value of 500 ppm, but not higher
than the Evacuate Alarm level. Factory default is 300 ppm. Refer to
Appendix for recommended alarm settings for other gases. Use the
Keypad to set the desired Spill Alarm level, and then press ENTER to
save that level and return to the previous screen.
EVACLVL – Sets the Evacuate Alarm level, adjustable from no lower
than the Spill Alarm level to 9999 ppm. Factory default is 500 ppm. Refer
to Appendix for recommended alarm settings for other gases. Use the
Keypad to set the desired spill level alarm level, and then press ENTER
to save that level and return to the previous screen.
LOG INT – Sets the interval at which measurements are logged to
memory from 1 to 9999 minutes. Factory default is 10 minutes. Note that
the logged measurements can be viewed using the PPM LOG function.
Use the Keypad to enter the desired value, and then press ENTER to
save that value and return to the previous screen.
LOOP – Adjusts the loop factor of the 4–20 mA current loop. Factory
default is 0.016 mA per ppm, which provides an output range of 0 ppm
(4 mA) to 1,000 ppm (20 mA). Use the Keypad to set the desired loop
factor, and then press ENTER to save that value and return to the
previous screen.
To facilitate loop zero and span checking, note that when the LOOP
function is selected the loop output is set to 20 mA, and upon exiting this
function the loop output is set to 4 mA.
