2. Watch log: Records 1 pressure channel (High resolution log selectable from 1 second data, for 9 hours data
storage, up to 16 second averaged data to provide 6 days of stored data). This log is circular- first data in last data
out. To save this data go to “Display column”/ “View Watchlog”/ Select the timeframe & start time, click OK. The
data will appear automatically in Excel. This is probably the best log to use for leak testing.
3. Fast log (X3): Three separate logs recording #1, #2 or #3 pressure channels only (or any combination: Low, High
or Delta (“Delta” will record a specific pressure spike or drop within a 1 second interval).
These three independent logs “Capture” the event with a trip point (similar to an alarm). This log records data
every second for a total of 1 hour. After the trip point is reached, the data recording will continue for 30 more
minutes and stop. There are 3 modes: 1. “Running” (continuously recording data points- waiting for a trip point), 2.
“Pending” (Trip point has been reached but waiting to finish recording the rest of the 30 minute data, 3. “Stopped”
(The trip point has been reached and 30 minutes has passed). After these logs have stopped, they can only be reset
using the Fastlog reset- “Configure column”/ Reset Instrument/ Reset Fast Log 1/2/3. The Fastlog data can be
saved in a Binary file (Graphical format) that allows zooming in or out on the pressure trend line as well as Min,
Max & Average readings. This data can also be saved in a “CSV” format to view in Excel.
Set Real Time Clock
1. Go to the Configure Column/ “Set Real Time Clock”, click “OK”. The window that appears on the screen is
comparing the “Host Standard Time” to the “Instrument’s Standard Time”. Click “OK” or type <enter>. This will
set the instrument time-clock to match the computer’s clock.
Note: The instrument doesn’t adjust for Daylight
Savings time. Setting the HDR clock uses the
computer’s time-clock it’s connected to.
