Gxp-8 for the eight automatic temperature detector circuit to measure the temperature of the eight-pass lead, in the automatic inspection mode: each lead after a pass, stay for 3 seconds to display the Communications and Navigation of the measured temperature. This instrument consists of two groups of high-brightness red LED shows the measured temperature, respectively, and through which the lead position. Instrument can also be manually selected through guidance, automatic and manual switch at this time with manual, push the micro switch to the choice of site selection to the needs of Communications and Navigation. This instrument consists of large scale integrated circuit, LED and high brightness red LED composed of PN junction temperature sensor. With a clear and intuitive readings, performance, reliability, precision, can be used in small cold storage, greenhouses, sheds, bearings and the need for multi-point temperature of the place. 

 Main technical parameters: 
 1. Measuring range: -20 ~ 150 ℃ 
 2. Measurement error: ≤ ± 0.5 ℃ 
 3. Resolution: 0.1 ℃ 
 4. Display: 3 ? digit red LED display with high brightness, channel by a separate digital display. 
 5. Power supply voltage: ~ 220V ± 10% 50H 
 6. Power consumption: <3W 
 7. Work: continuous work. 
 Use: 
 Instrument panel with temperature display window and display temperature derivative of Communications and Navigation of the pass and three button switches, have the text in the button next to the switch indicate the purpose: 
 1. --- Switch to power switch, click open, connected to 220 volts AC power, and then click to OFF. 
 2. Auto / Manual --- switch is not pressed before the instrument for the automatic inspection status, and is self-locking switch click, instrument choice of site for the manual states, this time pressing the button manually select the access point, click and then put each open, pass to the next derivative of the number, this state has to go to press the auto / manual switch, this switch bounce, back to the auto inspection state. 
 3. Manually select the point --- when the auto / manual switch to manually select points in the state press, this switch can only work, then each press pass to enter the next number of derivatives, do not follow the guide can be stopped on the original pass. The rear panel of the instrument sequence number 24, ranked 12 on the next row of 12, drawn on the row 8, the next row of eight, access 8 temperature sensors, to take on the row: 1,2,3 , 4,5,6,7,8, corresponding to the display through derivative: 1,2,3,4,5,6,7,0. (0 is equivalent to 8) on the red row of connected sensors (sensor positive) lower row: 13,14,15,16,17,18,19,20, then black line sensor (the sensor negative). 
 4. Instrument has dust cover, remove the operation, run out of recovery.
