Power Source
This product is intended to operate from a power module
whose power sourcewill not apply more than
250 volts rms
between the supply conductors or between either supply
conductor and ground. A protective ground connection by
way of the grounding conductor in the power cord isessen-

Groundingthe Product
This product is grounded through the grounding conductor
of the power module power cord. To avoid electrical shock,
plug the mainframe power cord into a properly wired recep-
tacle beforeconnectingto the productinputor output termi-
nals. A protective ground connection by way of the
grounding conductor in the power cord is essential for safe
operation.
Danger Arising From Loss of Ground
Upon loss of the protective-groundconnection, all accessi-
ble conductive parts(includingknobs and controlsthat may
appear to be insulating)can render an electric: shock.
----
Use the Proper Fuse
To avoid fire hazard, use only the fuse of correct type, volt-
age ratingand current rating as specified in the partslistfor
your product.
Refer fuse replacement to qualified service personnel.
Do Not Operate in Explosive Atmosphe!res
To avoid explosion, do not operatethis product in an explo-
sive atmosphere unless it has been specifically certified for
such operation.
Do Not Operate Without Covers
To avoid personal injury, do not operate this product with-

Trigger Points Trigger levels are automatically set
to the
90% and 10% points of the
incoming signal, to a resolution
that depends on the incoming
signal amplitude.

N
= Number of Averages
The minimum number of averagesis selectedby the AVERAGES button and the
69
buttons indecadestepsfrom 1to
10'. At Channel A repetition rates above approximately250 Hz the actual number of averages will be:
N
= [FREQ A (Hz) x 4 msec] + AVGS
N
= AVGS setting (below 250 Hz)
This typically leads to better than expected resolution in the displayed answer for small N with only minimal impact on
measurement time. Arming must be used when measuring only one event out of a pulsetrain (multiple events) with signals
a250Hz.
