2.2 Frequency Measurement
2.2 Frequency Measurement
• The maximum input voltage is 1000 VDC,
1000 Vrms, or 10
7
V•Hz.
However, for CATIII circuits, the maximum
voltage is 600 Vrms. Attempting to mea-
sure voltage in excess of the maximum
input could destroy the product and result
in personal injury or death.
• For safety, test lead connections must
always be made at the secondary side of a
circuit breaker.
Canceling the frequency
measurement:
Press REC•MEMO
Attenuation factor of the input voltage
(1/10
n
)
(n: Scale number)
Indication range: 0.5 Hz to 500 kHz
Move the function selector to
the V position and press
the REC
•MEMO button ("Hz
lights up).
2. Connect the red test lead to
terminal V.Ω, and the black
test lead to terminal COM.
3. Select the input level (1 to 4
using the RANGE button, in
accordance with the input volt
age.
4. Connect the test leads to the
measurement object, and read
the indicated value.
