Function Screens
The Function screens are used to display stored data and to set up the monitor.
From the Data Display screen, press any Keypad button to display the first Function Menu screen.
Next, use the Keypad buttons to move the arrow (>) on the display until it is next to the desired function,
and then press the ENTER button to select that function.
Once a function has been selected, use the Keypad to scroll through the displayed data or to change a
parameter associated with that function. Press ENTER to save newly entered parameters. Press the
QUIT button to return to the previous screen without saving.
Note that if no buttons are pressed within 90 seconds after selecting a function, the monitor returns to the
Data Display screen.
PPM LOG – Contains records of the last 200 measurements. Each
record shows the measurement’s date, time, and ppm level. Note that the
interval at which the measurements are logged is determined by the
LOG INT function.
Use the Keypad Up and Down buttons to change the record number by
a factor of 1. Use the Right and Left buttons to change the record
number by a factor of 10. Press QUIT to return to the previous screen.
In the example on the right, record #025 shows that a level of 425 ppm
was measured on 11/07/03 at 15:35.
Note that the PPM Log can be cleared as described in Section
Clearing
the Stored PPM Log, Alarm & Fault Data (Page
20).
ALARMS – Contains records of the last 30 alarm events, with the
monitor’s most recent alarm being shown when the Alarm screen is first
displayed. After 30 events have been recorded, the newest record
overwrites the oldest. Each record displays either LEAK, SPILL, or
EVAC including the date and time the alarm occurred. Use any of the
Keypad buttons to scroll through the other alarm records. Press QUIT
to return to the previous screen. Refer to
Working with Gas Alarms
(Page
18).
Note that the ppm levels at which alarms occur are set using the
LEAKLVL, SPILLLVL, and EVACLVL functions.
In the example on the right, record #03 shows that a spill event occurred
on 11/10/03 at 15:06.
FAULTS – Contains records of the last 30 fault events, with the
monitor’s current fault status being shown when the Fault screen is first
displayed. After 30 events have been recorded, the newest record
overwrites the oldest. Each record lists an event’s numeric fault code plus
the date and time the fault occurred. Use any of the Keypad buttons to
scroll through the other fault records. Press QUIT to return to the
previous screen. Refer to Working with System Faults (Page
18).
In the example on the right, record #15 shows that a Purge Flow Fault
<1000> occurred on 11/10/03 at 12:37.
