5.  Offset control switch. This and the offset toggle switch [10] are used to apply an offset 

signal to the probe from 0 to ±90μT in 10μT steps. See 

Using the Offset Control

.

6.  Sensitivity selector. Select x10 to achieve 0.1nT sensitivity. Does not modify offset. 
7.  Power switch. 
8.  Waterproof connection to probe. 
9.  Charge light, illuminated when internal batteries on charge. 
10. Offset toggle switch. See [5]. 
11. 4½ digit LCD display. Displays directly in microtesla at x1 sensitivity. See 

Using the 

Sensitivity x10 Control

. On x10 sensitivity the displayed value is a factor of 10 larger than 

the true value, e.g. if the displayed value shows 0.1 (100nT); then the true measurement 
equals 0.01 (10nT). Autoranging: decimal point shifts to LEFT when display value 
decreases below 10.00; RIGHT when display value increases above 19.999. Battery voltage 
automatically displayed at switch-on: 5V minimum.
