FUNCTION AND RANGE
HINTS AND COMMENTS
Switches the power ON and OFF. When switched on, the
built in microprocessor switches on all segments of the dis-
play then it runs a power-up test, checking the measuring-
logic of the Timer/Counter before the counter starts work-
ing. This test takes about 2 seconds.
If an error is found, an error code will be displayed. Try
switching the Timer/Counter off and on again. If error code
01 - 03 persists, call Fluke service. Look on the last page in
this manual for Phone No. and address.
WARNING:The power switch operates on the secondary
side of the transformer. The power cable must be
disconnected from the line outlet socket if it is necessary to
completely isolate the Timer/Counter from the line.
Error 01 = RAM memory error
Error 02 = Measuring logic error
Error 03 = Internal bus error
Error OF = Overflow in the counting registers
Selects one of the nine measuring functions available.
The cursor does not stop at FREQ C if no Input-C HF-input
is installed.
Reciprocal frequency measurement of the signal at Input-A.
Range:
0.1 Hz to 16 MHz (SINGLE measuring-time)
1 Hz to 160 MHz (0.2, 1, and 10 s measuring-time)
If the signal is sine shaped and the input AC coupled, the
minimum input frequency is 20 Hz (at specified sensitivity).
