of 90.0 ≤ 100.000 mV ≤ 110.0., apply the requested input, or apply an input in
the allowed range. Use the numeric keys to add the value. Push the Continue
softkey.
7. Apply the subsequent requested value as in step 5. Push the Continue softkey.
When you record a negative value, always start with ‘-’.
XWWarning
Some of the voltages required for calibration are dangerous. To
avoid injury or death from electric shock, do not touch live
conductors during high-voltage calibration. Put the source
device into Standby mode after each calibration step.
8. Continue to apply voltages as necessary. Make sure you follow the connection
instructions each time. Remember that the input jack configuration changes.
9. When you complete the last point in the subroutine, you are asked if you to keep
the new constants. If you keep the new constants, the calibration constants are
saved and the Calibration Status counter is incremented and the date is updated.
If you discard the constants at this point, the calibration has no effect, the
Calibration Status counter is not incremented, and the date does not change.
Some semiconductors and custom IC's can be
damaged by electrostatic discharge during
handling. This notice explains how you can
minimize the chances of destroying such devices
by:
1. Knowing that there is a problem.
2. Learning the guidelines for handling them.
3. Using the procedures, packaging, and
bench techniques that are recommended.
The following practices should be followed to minimize damage to S.S. (static sensitive) devices.
1. MINIMIZE HANDLING
2. KEEP PARTS IN ORIGINAL CONTAINERS
UNTIL READY FOR USE.
3. DISCHARGE PERSONAL STATIC BEFORE
HANDLING DEVICES. USE A HIGH RESIS-
TANCE GROUNDING WRIST STRAP.
4. HANDLE S.S. DEVICES BY THE BODY.

Fluke Corporation
5. USE STATIC SHIELDING CONTAINERS FOR
HANDLING AND TRANSPORT.
6. DO NOT SLIDE S.S. DEVICES OVER
ANY SURFACE.
7. AVOID PLASTIC,VINYL AND STYROFOAM
IN WORK AREA.
8. WHEN REMOVING PLUG-IN ASSEMBLIES
HANDLE ONLY BY NON-CONDUCTIVE
EDGES AND NEVER TOUCH OPEN EDGE
CONNECTOR EXCEPT AT STATIC-FREE
WORK STATION. PLACING SHORTING
STRIPS ON EDGE CONNECTOR HELPS
PROTECT INSTALLED S.S. DEVICES.
9. HANDLE S.S. DEVICES ONLY AT A
STATIC-FREE WORK STATION.
10. ONLY ANTI-STATIC TYPE SOLDER-
SUCKERS SHOULD BE USED.
11. ONLY GROUNDED-TIP SOLDERING
IRONS SHOULD BE USED.
