Capture Analysis Modes
LeakQ™ mode. The Imager is able to capture the leak data for
later use to evaluate the type of leak (quick connect, threaded
coupling, hose, open end) and estimate the size of the leak.
PDQ Mode™ (ii910 only). The Imager is able to detect, locate,
and capture potential partial discharges and evaluate the type of
partial discharge (external, internal, surface, or other). The data
includes information for later use to create pulse phase diagrams.
MecQ™ mode (ii910 only). The Imager is able to detect, locate,
and capture a picture of components that may have mechanical
deterioration and require further attention.
To select the capture analysis mode:
1. Open the tool menu.
2. Tap the Capture Mode icon to open the Capture Mode menu.
3. Tap for the LeakQ mode.
The icon on the tool menu and the display change to show the
selected mode.
ii910 only:
4. Tap for the PDQ Mode.
5. Tap for the MecQ mode.
Online tools and calculators are available to create reports with
(data) captures that use the LeakQ, PDQ, and MecQ modes.
The capture analysis modes show on the display when the
on-device option is turned on. When on, a portion of the analysis
shows on-screen at the time of capture (see Settings and
Operating Conditions).
LeakQ™ Mode
LeakQ mode automatically determines the distance to the
target (a leak that shows inside the circle on the display).
When a leak is detected and the Imager can determine the
distance, the LeakQ value on the display gives an indication
of the size of the leak. The value is based on the measured dB
SPL value and the distance.
If a leak shows inside the circle on the display:
• Values for DISTANCE and LeakQ Scale show on the
display.
or
• NO TARGET FOUND shows on the display when no leak
is detected inside the circle.
If the Imager cannot automatically determine the distance, this
pop-up message shows on the display:
UNABLE TO ESTIMATE DISTANCE
If the Imager is unable to determine the distance, or you want
to override the estimated distance, you can input the distance
manually.
To input the distance manually:
1. Tap on the message to open a numeric screen and enter
the distance.
The Imager uses the entered distance to calculate the
LeakQ values.
Note
Stabilize the Imager for a few moments as it calculates
the values.
2. Press the Capture button to make a more precise
calculation.
