1. Refer to Clamp-on Calibration procedure for calibrating
zero flow [Delta-T Offset].
2. Refer to Section 3.6.7a Fluid Speed of Sound Calibration
for Calibrating sound speed.
3. Scroll and highlight [Peak Detection] and press [ENTER].
Select [Automatic] for the meter to automatically pick
the [Peak %]. If you frequently see E6: Cycle Skip errors,
please contact Factory.
3.6.7 Fluid speed of sound calibration
In order to perform Speed of sound (SOS) calibration it’s
necessary to install VitalityTM PC Software application ver.
1.5.0 or later. SOS calibration procedure is described in the
CAL-TRIM-TEST section of Vitality Help manual which can be
launched from application’s main menu.
The XMT1000 can calibrate the fluid speed of sound (SOS)
after installation, provided the operator knows the fluid SOS
under the current flow conditions. The measured fluid SOS
should be within the accuracy specification after following
the standard installation procedures. This SOS calibration
is for fine-tuning of the XMT1000 meter under the on-site
installation conditions and maintaining the high accuracy
performance.
3.6.7a Fluid SOS calibration procedure
SOS calibration will be done on each channel. After
calibration, the measured SOS from each channel, and the
composite channel, shall read within ±1 ft/s (or 0.3 m/s)
of expected value. Calibrate the fluid SOS as per below
procedure.
Calibration Procedure:
1. Open Panametrics Vitality. Click on [Connect].
2. Select instrument model and communication Port.
