	Due to limitations in the hardware, the actual DataInterval must be a multiple of 8. If you try to set a DataInterval that isn't a multiple of 8, the library will automatically round down to the nearest multiple of 8. So if you set DataInterval to 31, you'll end up with an actual interval of 24ms.		Due to limitations in the hardware, the actual DataInterval must be a multiple of 8.

			The 1046_1 has an improved calibration routine which takes approximately 3 seconds to complete when the channel is first opened. You should have your program wait a few seconds before polling for data, or you can catch the exception and retry until the request succeeds. If you want to get data as early as possible, use an [[Using Events\|event handler]] instead of polling.

	If no documentation is available for your strain gauge, it’s possible to use a multimeter to determine how to connect it, provided there are no electronics in the sensor. First, measure resistance between the 4 wires. There are 6 combinations - two combinations will have a resistance 20-40% higher than the other four. Choose one of these high-resistance combinations, and wire it into 5V and G on the 1046. Connect the other two wires into +/-. Apply a load, if the V/V responds in the opposite way to your expectations, flip the +/- wires.}}		If no documentation is available for your strain gauge, it’s possible to use a multimeter to determine how to connect it, provided there are no electronics in the sensor.

	Load cells output a small voltage proportional to the amount of strain they are currently experiencing. The rated output for most load cells at full load is in the order of millivolts, so when you’re only straining the load cell at a fraction of its full load, you will get very small values.

 Some wheatstone bridges, most often those produced from silicon and used in pressure sensors, will have a very wide offset, and large manufacturing variation in the offset. This will restrict the gain to lower settings, particularly if the application must support a number of deployed systems with the expected variation. Fortunately, the very high precision electronics used in the 1046 means that in many application, higher gain is not necessary to get adequate accuracy and resolution.
