5.2.1 Mounting

The UUT can be attached directly to the shaker head using a 1/4-28 stud. Adaptor studs and

plates are available for mounting sensors with different size mounting threads. See Table 2

below.

NOTE: The stud or adaptor plate should be mounted finger

tight only, not exceeding 10 in-lb (112 N-cm) into the shaker

head. Exceeding the maximum torque may damage the

shaker. It is recommended to use the open end wrench when

mounting sensors to stabilize the shaker armature.

A specially designed angular plate is available for calibrating the 993B-7-M12 triaxial

accelerometer. This plate will excite all three axes simultaneously, resulting in 0.57 g per axis.

See section 6.0.

5.2.2 Power ON/OFF

Turns on the shaker for approximately 90 seconds. The unit will default to the previously

selected options. To defeat the auto shutoff feature and enable continuous operation, hold down

the FREQ button while turning the unit on. All three frequency LEDs will briefly illuminate to

indicate the shaker is in CONTINUOUS operating mode. The unit will now operate until the

ON/OFF button is pressed again. When the unit is turned off, it will revert to the AUTO-OFF

mode.
