Temperature Sensor:
The LabJack U6 has a temperature sensor located very close to the AIN0-AIN3 screw-terminals. Accuracy is ±2 degrees C (max). This sensor is particularly useful for thermocouple cold junction compensation (CJC).
Fixed Current Outputs
The LabJack U6 has 2 fixed current outputs of 10 μA and 200 μA. These are useful for measuring resistance.

TC 직접 연결(K-type TC 위주) 관련::
* 아래 사양은 T7 및 T7-Pro도 동일합니다.
At 900 deg C, a type K thermocouple gives you about 37.3 mV, so you would use the +/-0.1 volt range on the U6.
(K-type 900도 측정시 37.3mV여서 +/-0.1 volt range 를 사용해야 합니다)
With resolution=8, the noise-free voltage resolution of the U6 is about 6 uV, so temperature resolution is roughly 0.15deg C.
(Resolution 인덱스 8 사용시, 6.3uV, 0.15 deg C)
With resolution=12, the noise-free resolution of the U6-Pro is about 1 uV, so temperature resolution is roughly 0.025deg C.
(Resolution 인덱스 12 사용시, 1uV, 0.025 deg C)
요약(최대 K-type 900도 기준):
1. U6는 6.3uV 0.15 deg C 해상도 가능 ( 단, +/- 0.01mv range(최대 온도 250도) 사용시 2.4uV, 0.06 degC 가능)
2. U6-Pro는 1uV 0.025 deg C 해상도 가능

Optional Accessories:
The CB15 is a simple screw terminal breakout for the DB15 connector. The CB37 is a simple screw terminal breakout for the DB37 connector. The EB37 experiment board also provides screw terminals for the DB37 connector, and in addition provides a solderless breadboard and useful power supplies.
The RB12 provides a convenient interface for the U6 to industry standard digital I/O modules, allowing electricians, engineers, and other qualified individuals, to interface a LabJack with high voltages/currents. The RB12 relay board connects to the DB15 connector on the LabJack, using the 12 EIO/CIO lines to control up to 12 I/O modules. Output or input types of digital I/O modules can be used. The RB12 is designed to accept G4 series digital I/O modules from Opto22, and compatible modules from other manufacturers such as the G5 series from Grayhill. Output modules are available with voltage ratings up to 200 VDC or 280 VAC, and current ratings up to 3.5 amps.
The LJTick-Divider (LJTD) signal-conditioning module is designed to divide 2 single-ended higher voltage analog signals down to 0-2.5 volt signals.
The LJTick-DAC (LJTDAC) provides a pair of 14-bit analog outputs with a range of ±10 volts. Plugs into any digital I/O block, and thus up to 10 of these can be used per UE9 to add 20 analog outputs.
The LJTick-InAmp (LJTIA) signal-conditioning module provides two instrumentation amplifiers ideal for low-level signals such as bridge circuits (e.g. strain gauges) and thermocouples. Each amplifier converts a differential input to single-ended. Since the U6 has a programmable gain instrumentation amplifier built-in, this tick is only useful in particular situations.
The LJTick-RelayDriver (LJTRD) allows 2 digital I/O lines on a U6 to each control a relay or other moderate load up to 50V/200mA.
The LJTick-CurrentShunt (LJTCS) signal-conditioning module is designed to convert a 4-20 mA current loop input signal into a 0.47-2.36 volt signal.
The LJTick-Proto (LJTP) consists of an 8x8 grid of holes for prototyping custom signal-conditioning ticks for the LabJack U6.
