The GK-404 is a palm sized readout box that displays the vibrating wire value, as well as the
temperature in degrees centigrade.
3.1.1 Operating the GK-404
Before use, attach the flying leads to the GK-404 by aligning the red circle on the silver
“Lemo” connector of the flying leads with the red line on the top of the GK-404 (Figure

(Other functions can be selected as described in the GK-404 Manual.)
The GK-404 will continue to take measurements and display readings until the unit is
turned off, either manually, or if enabled, by the Auto-Off timer. If no reading displays or
the reading is unstable, consult Section 5 for troubleshooting suggestions.
