怎樣不開蓋用標準源修正呢作者: swife 時間: 2008-10-24 00:32
參考說明書的操作，沒有的話向辦事處的人咨詢，可以進入它的校準模式進行校準作者: 黎明 時間: 2008-12-11 19:11
打電話打FLUKE公司問一下啊！作者: gaobingic 時間: 2008-12-11 20:22 標題: 好好看看Fluke8845/8846校準手冊的3-25頁一下介紹！ Adjustment (Calibration)
Meter adjustments, or calibration, should be performed at the desired interval, or
whenever a verification test indicates a Meter function is out of tolerance. The Meter
accuracy will stay within specifications only if the adjustment procedure is performed at
regular intervals. A one-year interval is adequate for most applications. The Meter’s
accuracy specifications are not valid beyond the one-year interval.
Meter adjustments are accessed only through the remote interface with a series of
adjustment steps. The remote program directs the test equipment to apply a series of
shorts, opens, voltages, currents, and capacitance (8846A only) to the Meter. At each
step, the Meter internally makes the necessary adjustment to bring the Meter into
specification. No internal mechanical adjustments are necessary.
Using an automated, computer-controlled procedure, the calibration and verification
procedures can be performed on the Meter in under 60 minutes. A sample adjustment
program is listed on the “Sample Adjustment Program” section later in this manual. A
MetCal program is available at www.fluke.com to adjust the Meter.
The Meter’s adjustments are password protected to prevent accidental or unauthorized
adjustments. The security password must be entered through the front panel or remote
interface before adjustments can be made to the Meter.
Unlocking the Meter for Front-Panel Adjustments (Calibration)
To unlock the Meter for adjustments from the front panel:
1. Press I.
2. Press CAL.
3. Press UNLOCK CAL.
Press the soft key labeled -- to decrement the character or ++ to increment the
character. The character can be set to 0 through 9, A through Z, period (.), and
dash (-).
To move to the next character, press -->.
4. Press ENTER to enter the password and unlock the Meter for adjustments.
Find the CALIBRATION:SECURE:STATE command in the “Supported SCPI
Commands” section of the 8846A/8845A Programmers Manual for information on
unlocking the Meter for calibration.
The Meter is shipped from the factory with the password set to FLUKE884X.

請問5# gaobingic：
Fluke8845A/8846A是不是需要通過MET/CAL才能調(diào)校？
請問你有在MET/CAL上運行的Fluke8845/8846調(diào)校程序么？？
能不能給我一份啊！！
謝謝！！
