VARIOUS OPERATING MODES
SCALING
Two external resistors may be used to alter the
full scale reading of the meter - see table for
sample values.
following formulae to calculate Ra and Rb.
Select the nearest available standard resistor.
To achieve optimum accuracy, use 1% metal
film resistors. Ensure solder link La is cut
when fitting Ra.
