Revision 4.6 3/2004

isfy this requirement.

Delayed initiation of unattended measurement activities
requires the set up of

both

the Event Timer and data

logging function.

Section 25.1

Event Timer Set-Up

To program the HHC system for delayed monitoring and
data logging follow the steps below.

The event timer sets the starting and ending times for
unattended monitoring to be performed during a future
time period. The Event Timer function is programmed as
follows.

Step 1

With the HHC system on and measuring pres-

sure press the set up key.

SET

UP

Step 2

Using the arrow keys select the event timer,

designated EvntTimr, option on the set up menu. When
selected the text “EvntTimr” will ﬂ ash on the display.

EvntTimr Dampen

LeakRate Status

Step 3

With the text EvntTimr selected and ﬂ ashing on

the display press the enter key.

ENT

The HHC system will respond by displaying:

HHMMSS Start

XXXXXX

where:

HH = hours in military time
MM = minutes (0-60)
SS =

seconds (0-60)

Use the number keys to enter the hours, minutes and
seconds in the corresponding entry ﬁ elds to establish the
start time.

Step 4

When entered the start time will look as follows

for a time of 9:30 PM.

213000 Start

XXXXXX

Step 5

When the desired start time has been input and

appears on the display press the enter key.

ENT

The HHC system will respond by displaying:

HHMMSS Stop

XXXXXX

Step 6

Enter the desired stop time using the number

keys. When properly entered a stop time of 11:30 PM
will look as follows:

HHMMSS stop

233000

Step 7

When the desired stop time has been input and

appears on the display of the HHC system press the
enter key.

ENT

The HHC system will respond by displaying:

Event Timer

Disable Enable

Step 8

Use the right arrow key to select the word Enable.

When selected the word Enable will ﬂ ash on the display.

Event Timer

Disable Enable

Step 9

With the word Enable ﬂ ashing press the enter key.

ENT

Section 25.2

Data Log Set Up for Operation

with the Event Timer

Automatic data logging must be set up to control the
data logging parameters to be followed in time delayed
data logging. For delayed data logging the logging func-
tion must be set up as follows.

Step 1

With the HHC system on and reading pressure

press the data log key.

DATA

LOG

The HHC system will respond by displaying the following:

THE LAST DATA LOG MENU SCREEN USED

Step 2

To program the HHC system for time delayed

data logging use the arrow keys to locate and select the
word “Auto” in the data log menu. When selected the
word Auto will ﬂ ash on the display.

Auto Manual

Review Off

Step 3

With the word Auto ﬂ ashing press the enter key.
