Frequency measurements
The Model 2002 can make frequency measurements from 1Hz to 15MHz through its INPUT
HI and INPUT LO terminals, and from 1Hz to 1MHz through its AMPS and INPUT LO termi-
nals. Assuming “BENCH” reset conditions, the basic procedure is as follows:
1.
Connect test leads to the INPUT HI and LO terminals of the Model 2002. Either the front
or rear inputs can be used; place the INPUTS button in the appropriate position.
NOTE
A bench reset defaults the frequency input terminals to INPUT HI and LO.
2.
Select the FREQ function.
3.
Connect test leads to the source as shown in Figure 7 (top).
CAUTION
Do not exceed 1100V peak between INPUT HI and INPUT LO, or instru-
ment damage may occur.
4.
Take a reading from the display.
The procedure for measuring frequency with the AMPS and INPUT LO terminals is similar.
However, the FREQ function has to be con gured to use the current terminals (the connection
diagram is shown in Figure 7 (lower)). Perform the following steps to select the AMPS and IN-
PUT LO terminals:
1.
Press the CONFIG key and then the FREQ key.
2.
Using the cursor keys (
and
), place the cursor on INPUT-TERMINALS and press
ENTER.
3.
Place the cursor on CURRENT and press ENTER.
4.
Use the EXIT key to back out of the menu structure.
CAUTION
Do not apply more than 2.1A, 250V to the AMPS input, or the amps protec-
tion fuse will blow.
