(3) “ FUNCTION ” Select Switch
Selects “ INPUT COUNTER ” functions.
“ COUNT ” …… Accumulated total counter
Counts the number of incoming pulses at “ SIG ” terminals.
“ FREQ 1S ”…… Frequency counter with one second gate
Counts the number of incoming pulses at “ SIG ” terminals for a period of one
second → Displays it for one second → Reset to “ 0 ” . The cycle above is
repeated.
Unit of measure displayed on the counter …… “ Hz ”
“ FREQ 10S ” … Frequency counter with 10-second gate
Counts the number of incoming pulses at “ SIG ” terminals for 10 seconds → 2
sec. hold displayed →“ 0 ” reset.
This cycle is repeated.
Unit of measure displayed on the counter …… “ Hz ”
“ PERIOD ” …… Period counter with 1MHz pulses
Counts the period of incoming pulses at “ SIG ” terminals against the 1MHz
internal pulses and displays it, latched.
Unit of measure displayed on the counter …… μ s
“ RATIO ” …… Gated accumulated total counter
Counts the number of incoming pulses at “ SIG ” terminals at the intervals of
pulses incoming through “ GATE ” terminals and displays it, latched.
(4) “ RESET ” Pushbutton Switch
Upon depression, the “ INPUT COUNTER ” is reset to “ 0 ” .
(5) “ INPUT COUNTER ”
An 8-digit LCD accumulated total counter. Its functions are selectable with “ FUNCTION ” select switch.
3. Output Functions
(1) “ FREQUENCY ” Preset Switch
Establishes the reference frequency of output pulses with 4-digit decade switch.
Preset coverage: 1 to 9999Hz (in 1Hz steps)
(2) “ RATING ” Select Switch
Selects the decimal point of the “ FREQUENCY ” reference frequency.
“ 1 ” …… The decimal point of 4-digit decade switch is □□□□ . Hz
“ 10 ” …… The decimal point of 4-digit decade switch is □□□ . □ Hz
“ 100 ”…… The decimal point of 4-digit decade switch is □□ . □□ Hz
“ 1K ” …… The decimal point of 4-digit decade switch is □ . □□□ Hz
“ 10K ”…… The decimal point of 4-digit decade switch is 0. □□□□ Hz
(3) “ % SETTER ” Select Switch
Selects % frequency reduction of the reference frequency.
“ 100 ”…… Provides the reference frequency output with the decimal point chosen as above.
“ 75 ” …… Provides the reference frequency output × 0.75 with the decimal point chosen as above.
“ 50 ” …… Provides the reference frequency output × 0.5 with the decimal point chosen as above.
“ 25 ” …… Provides the reference frequency output × 0.25 with the decimal point chosen as above.
“ 0 ” …… No output is provided.
(4) “ PRESET ” Switch
Presets the number of output pulses with 8-digit decade switch.
Upon “ START ” button depression, the checker produces the number of pulses preset before it
comes to stop pulse generation automatically.
Preset coverage: 1 to 99999999 P (in 1P steps)
