This key has two functions The first is to increase either the SPAN or MASS parameters when used in conjunction with these keys The second use is to toggle between the Hz and the newton measurement modes This key has two functions The first is to decrease either the SPAN or MASS parameters when used in conjunction with those keys The second use is to toggle between the Hz and the pound measurement modes The memory keys allow up to 3 sets of belt parameters to be stored in the meter registry Pressing the MEM 1 key recalls the first set of belt parameters and likewise for MEM 2 and MEM 3 To store the belt parameters to a key the belt span and mass parameters must first be entered and then immediately after release of either the SPAN or MASS keys the appropriate MEM key should be pressed Two beeps indicate that the parameters have been successfully assigned to the key 3 2 Audio visual display The SKF Belt Frequency Meter is an interactive tool It provides both visual and audible communication with the operator Each signal or combination of signals has a meaning While all these signals are discussed in other sections of this manual a compilation of all the available signals will be presented here Generally visual signals alone give measurement results while audible signals either alone or in combination with a visual signal indicate some operational step N 7 Frequency mode Visual measurement Ibs results displayed as h
