10 SOUND MODE/DETECTION MODE

Your Covermeter indicates the presence of a reinforcement bar visually and
audibly:
• The DISPLAY indicates the presence of a reinforcement bar in the form of a
signal strength indicator bar and a depth of cover reading.
• The LED on the search head starts to glow as the search head is brought
near a reinforcement bar. The intensity of the LED increases as the search
head gets closer to the bar.
• Although the display and the LED indications are important, it is likely that
you will also rely upon the SOUND emitted by the internal speaker. This is
the main indication of the presence of a reinforcement bar.
Your Covermeter has three sound/detection modes; Locate, Maxpip™ and
Under Cover.
MENU / SETUP / SOUND MODE

10.1 Locate

In this mode, the pitch of the sound from the Covermeter increases as the
search head gets closer to a bar.
Sound volume can be adjusted -
The apparent volume of the sound can also be adjusted by changing the
sensitivity setting.
Adjusting sensitivity
The sensitivity setting is indicated by the variable wedge-
shaped symbol on the display. To increase the sensitivity,
press . To decrease the sensitivity, press
Typically, set the sensitivity to produce a slow 'clicking' sound
in the absence of metal. With the sensitivity set at this level you will be able to
differentiate quickly between bars of the same size located at different depths.
If the sensitivity is optimised, the pitch of the sound will consistently give a good
guide to the extent of cover; shallower-than-average bars will produce a clearly
noticeable, more intense sound, which will draw your attention to such bars.
