1. Safety instructions
The microsecond counter conforms to safety
regula-tions for electrical measuring, control and
laboratory equipment as specified in DIN EN
61010 Part 1. It is to be operated in dry rooms
as appropriate for the use of electrical equip-
ment.
Safe operation of this equipment is guaranteed
as long as it is used as stipulated. However,
there is no guarantee of safety if the equipment
is used incorrectly or carelessly.
If there is any suspicion that the equipment can
no longer be operated without risk (e.g. if visible

2. Description
The microsecond counter is a compact counter for
measuring time in microseconds. It is especially
well suited for measurements made in conjunction
with Kundt's tube and the microphone box.
The counting process is start via the Start input
and halted via the Stop input. The count is au-
tomatically reset back to zero on each start.
Both inputs respond to rising edges and have
internal pull-up resistors.
The microsecond counter 1017334 is for opera-
tion with a mains voltage of 115 V (±10%), and
the unit 1017333 is for operation with a mains
voltage of 230 V (±10%).
