Page 3: Introduction / Overview
+SIG +EXC The resistance of the strain gauge can be between 85 and 5000 Ohms. The T24-SAf can support up to 4 350Ohm strain gauges bridges attached in parallel (At the expense of reduced battery life). The cable lengths between the T24-SAf and the gauges should be kept below 3 meters and generally as short as possible. -
Page 4: Configuration
Toolkit software and a T24-BS base station to allow your computer to communicate with T24 telemetry devices. Calibration Please Note: The calibration feature is not available for the T24-SAf. Installation T24 Toolkit To configure the devices we must use the T24 Toolkit software application. This can be downloaded from our web site or may be shipped with your products. -
Page 5: T24 Toolkit
If no communications can be established the toolkit will remain on this page. You will need to check that the base station is powered and that it is connected to the converter correctly. Mantracourt Electronics Limited T24-SAf Fast Strain Gauge Acquisition Module User Manual... -

If you connect successfully the toolkit will change to the Information page. If the pairing fails try again. NOTE: Pairing with the toolkit will not change the radio configuration settings of the connected device. Mantracourt Electronics Limited T24-SAf Fast Strain Gauge Acquisition Module User Manual... -

The above charts show the traffic from a Wi-Fi network and it can be seen to be operating over channels 6 to 9 and it would be best (though not essential) to avoid using these channels. Mantracourt Electronics Limited T24-SAf Fast Strain Gauge Acquisition Module User Manual... -
Page 8: Data Provider Monitor
Data Provider Monitor NOTE Prior to version 1.1.91 of the T24 Toolkit the value shown for a T24-SAf will look like random characters because the data packet from the T24-SAf contains 10 values not just the normal single value. Version 1.1.91 and later will show the correct value but will only log at 200Hz. -

CV is the correlation value and indicates how well the signal can be decoded. This ranges from 55 which is a poor quality signal and 110 which is an excellent signal. Mantracourt Electronics Limited T24-SAf Fast Strain Gauge Acquisition Module User Manual... -
Page 13: Channel And Encryption
Note that some devices such as the T24-AO1 analog output module will allow pairing to an acquisition module. When pairing it will alter the T24-SAf settings to match those of the analog output module. NOTE: Early acquisition module do not yet utilise the encryption keys so these should be left at all zeros. -

Allows turning on or off the application of a shunt cal resistor to the bridge input. You must remember to turn this off before exiting the Toolkit software. nV/V Shows the output value so the effect of the Shunt Cal can be seen.

Range underwater is only a decimetre or so depending on packet rate. Best performance underwater is obtained by using low packet rates and immersing water-proofed antennae rather than water-tight enclosures containing the antennae. Mantracourt Electronics Limited T24-SAf Fast Strain Gauge Acquisition Module User Manual... -
Page 18: Power Supply / Battery
This is due to voltage drops caused during the high current phase of the measurement cycle. In the case of a T24-SAf strain gauge input module 300mA required for 250uS. Batteries with an internal resistance of less than 150mOhm will not require the additional inline capacitor module. -
Page 19: Battery Types
The unit comes pre-configured to provide a charging current of 466mA suitable for VARTA LIP653450. This module also supports additional batteries providing a charge current of 133mA via the removal of the leaded resistor (non surface mount).

This problem becomes apparent when attempting to communicate with high peak current acquisition modules such as a T24-SAf using the T24 Toolkit or power cycling when the battery is near the end of its life. In normal operation (Low power mode) with an analog output module or the T24-SAf is connected to an uninterrupted battery this module is generally not required. -
