76 Loading Software

To load instrument software in the test tool, the Fluke-43-123-19x ScopeMeter Loader program is required. Power the test tool via the power adapter input using the BC190 Power Adapter. Some units having serial numbers below DM7000000 can give the error message Error 8 No connection possible with UHM because they require a 20V 1VDC (0.5 A) voltage on the Power Adapter input (units having an Intel FlashROM). For this purpose, a special supply cable, also advised for calibration, can be ordered...

Batident

The BATTIDENT line (pin 90) is connected to R508 on the Power part, and to a resistor in the battery pack. If the battery is removed, this is signaled to the D-ASIC (BATTIDENT line goes high). The MAINVAL signal (pin91) is supplied by the P-ASIC, and indicates the presence of the power adapter voltage (high present). The FREQPS signal (pin 93) is also supplied by the P-ASIC. It is the same signal that controls the Fly Back Converter control voltage FLYGATE. The D-ASIC measures the frequency in...
