What are the Millar Catheter pressure ranges
Millar Mikro-Tip Pressure catheters have an operating range of -760 to 4000 mmHg; however, their linear operating range is -50 to 300 mmHg. For any pressures outside the linear range the user must perform a nonlinear calibration over the range of...
Catheters with a 'PVR-' prefix CAN NOT be used with the older Millar ARIA Pressure-Volume unit, but catheters with an 'SPR-' prefix can be used. The internal catheter wiring differs between the 'PVR-' and 'SPR-' catheters, so the former is not...
Fast Response Output is a LabChart extension that allows you to control the digital outputs on 30-Series and 35-Series PowerLabs and the analog outputs on 20-Series, 25-Series, 30-Series, and 35-Series PowerLab units (other models not supported), for...
LabChart Reader v7.2 is the latest version that was supported on Mac OS 10.4. For further technical assistance with this or any other issue, please contact ADInstruments Technical Support by clicking HERE.
What are the limitations of Smart Pad placement if using multiple telemetry set-ups in the same lab?
To avoid any cross-talk when using multiple Telemetry Research telemeters in the same laboratory, the smart pads should be placed as far apart as possible. The SmartPad charges the Telemeter using an electromagnetic field generated above and below...
How is time point "T-end" determined by the ECG Analysis Module?
The ECG Analysis Module estimates the T-end for a non-rodent ECG by first finding the T-wave peak time point (T-peak). Following the peak, a least squares fitted line is drawn from 70% to 30% amplitude on the falling slope. T-End is then marked as...
Why is there a knob on the ML309 Thermistor Pod?
The knob on the ML309 Thermistor Pod is only active during delta (Δ) temperature readings and has no effect on the signal coming from the pod when set to absolute temperature readings. When the pod is set to record ΔT, the knob can be used to set the...
What do the different tBase status lights mean?
The status light at the front of the tBase provides information on the communication status between the tBase and the telemeter. The different status lights are summarised in Table 1. Table 1: What do the tBase status lights mean? The status lights...
How do I update LabChart Lightning?
LabChart Lightning automatically checks for updates when the software starts up and a notification will pop up if there is a newer version available. One can also manually check for an update by going to Help menu and clicking on Updates and then...
What are projects and recordings in LabChart Lightning?
When you open LabChart Lightning for the first time, you’ll see a recording in front of you. You can think of this as being similar to a LabChart 8 File or experiment. You can sample data straight away just like in LabChart 8. However, a key new idea...
How do I get more licenses for LabChart Lightning?
Request new licenses through the LabChart Lightning licensing site For further technical assistance with this or any other issue, please contact ADInstruments Technical Support by clicking HERE .
How do Readouts display sampled data
Readouts always show the most recent data in your recording. If you’re sampling, readouts display the data that is currently being sampled or calculated. If you’re not sampling, readouts will show that is on your cursor in the recording. For further...
Can rat biopotential telemeter leads be cut?
The leads of rat biopotential telemeters (TR50B, TR50BB, TRM54PB and TRM56SP) are ~25cm in length to ensure ample lead is provided for recording of biopotentials and to support reuse of the telemeters. It is NOT recommended that biopotential leads of...
Should I cut mouse biopotential telemeter leads when implanting?
The leads of mouse biopotential telemeters (MT10B) are ~8cm in length. To prevent damage to the skin of the mouse during long term implantation, it is NOT recommended that excess lead length is coiled subcutaneously. Therefore, the leads should be...
Why can't I find a telemeter with ConfigSoft even though I've switched it to Active Mode?
If a telemeter has been placed in Active Mode but cannot be found by the Configurator System using the Search for Telemeter function of ConfigSoft, it is likely that the telemeter battery has been discharged. In this case the status light of the...
What lengths of catheter are available for pressure telemeters and what are the possible applications of each?
Pressure telemeters (TRM54P, TRM54PB, TRM54PP and TRM56SP) come with a 9cm pressure catheter as standard, however they can be customised with 15cm or 25cm catheters on request. Suggested catheter lengths for different applications are summarised in...
What is Cohousing Mode for rat telemeters?
Rats are a social species and single-housing, which is often associated with telemetry studies, can affect both their physiology and behaviour. To solve this, studies often use unimplanted cage mates, however this increases the cost of the experiment...
Can I use the CEC-10E with Ventri-Cath PV catheters?
The CEC-10E pressure-volume interface cable connects legacy dual and single pressure PV catheters to the MPVS Ultra. It is not compatible with Ventri-Cath pressure volume catheters. For further technical assistance with this or any other issue...
How do I disable the rat telemetry Cohousing Mode?
Before they are returned to normal single housing operation or before the SmartPads are used for recharging explanted telemeters, Cohousing must be disabled on both the Primary and Secondary SmartPads using the Configurator System. 1) In the SmartPad...
Telemeters and SmartPads must first be configured for normal recording conditions. For instance, using ConfigSoft, two telemeters would be set up to transmit data on Frequencies 23 and 24 and the SmartPads would be set up to receive data on...
