【Brief introduction of goods】：
First, gathering meter outline
The TT103 migration type temperature type gathering meter is one kind of memory type real-time temperature data acquisition instrument, some three channels (TT103) and seven channels (TT107) two kind of specifications. Each channel allots the corresponding thermo-element, may at the same time to three channels or seven channels by the 1Hz gathering rate gathering 600 seconds data. The data saves in the instrument non- is easy to lose saves in EPROM, after gathering finished does not need the battery then for a long time the data preservation in the instrument, until next time gathering when only then renews the data. The replacement instrument battery cannot create the data missing.
The TT103 migration type temperature data acquisition meter has the standard the RS232 connection, may be direct and the PC machine serial mouth docking. The software supplements which using the gathering meter may gather in the meter the data transfer to PC machine in. This software moves under Windows, contact surface friendly, the function is rich. May on the screen demonstrate or prints each channel on the printer the temperature data and along with the time variation curve.
TT103 migration type temperature data acquisition meter volume small, the use is simple, but widely uses in surveying the wave ridge to weld, the backflow welding machine welding temperature craft curve.
Second, technical specification
1. measures the warm scope: 0~300 ℃
2. measures the warm precision: ±2 ℃
3. sampling gaps: 1 second
4. biggest sampling time: 600 seconds
5. sampling pass the magical skill: 3 (or 7)
6. sensors types: Nichrome nickel silicon (K) thermo-element
7. power sources: But rechargeable battery
Third, gathering meter kneading board
Data acquisition kneading board
Indicating lamp: When the condition switch is in "gathering" the position, the indicating lamp bright half second, comes for half second, expressed the normal sampling, the sampling time achieved when 600 seconds, the indicating lamp extinguishes. When the condition switch is in "the dump" the position, the indicating lamp lightens, until the data transfer finished, the indicating lamp extinguishes.
Fourth, data acquisition
1. and fixes the thermo-element insertion corresponding channel to measured warm lights, and will gather the meter to put to the appropriate position.
2. allocates move set clock for the condition switch "gathering" the position, then turns on the power switch, the indicating lamp starts to glitter (bright half second, extinguishes for half second), the expression gathering meter work is normal.
3. starts welds the stove the conveyer belt, lets gather the meter to enter in the stove along with the conveyer belt.
4. gathers the meter to come out after the stove, allocates move set clock for the condition switch "the dump" the position, again closes the power switch.
Attention: Dials the switch order not to be possible to invert, otherwise can lose the data. If gathering surpasses 600 seconds in the stove time, instructed the lantern festival automatically extinguishes, this time still had to allocate move set clock for the condition switch "the dump" the position, then closure power switch.
Fifth, data dump
1. uses to gather the communications cable which the meter supplements connects the instrument and the PC machine serial mouth. On the communications cable uses is 25 needles plugs, the user may insert it in the PC machine 25 needles serial mouths.
2. moves the gathering meter software in PC machine.
3. chooses "the receive string mouth data" in the menu the function (or chooses corresponding function in tool strip button), after waits the screen to appear the prompt to turn on the gathering meter power source, PC machine starts to receive the data.
After 4. data receives finished closes the gathering meter power source.
Attention: If appears "the serial mouth choice mistake", usually is because the software establishes the serial mouth creates not identically with the gathering connection to the PC machine serial mouth. Only must in "pass chooses unguardedly" center chooses another serial mouth, again presses "the start" the key then.

【Remarks】：
Sixth, gathering meter software installment
This software may (or above edition) under moves in Chinese Windows95. Please according to below step installment;
1. establishes a new folder on the hard disk
2. stochastic will bring on 3 floppy disks all contents duplicate to the new folder in.
In 3. movements folders Setup.Exe, carries on the installment according to the screen prompt.
Seventh, gathering meter software function
1. receives strings mouth data
Eighth, replaces the battery
Gathers the meter to use the 9V level to fold the battery, replaces when the battery will have the gathering outer covering four tight screws to take down, turns on the top head then to see will clamp to the battery.
Tight screw tight screw
Tight screw tight screw
