13. SCALE amp OFFSET SETUP For DC voltmeters amp ammeters a scale factor of 1 and an offset of 0 are used for direct readings in milli volts or milliamperes Decimal point selection does not affect the displayed digits For example 0 20V or 0 20 mA signals can both be displayed as 0 20000 A full scale of 20000 may be displayed as 20 000 mA or 20000 pA Use with a current shunt will require a scale factor to be set For example for a 500 100 500A 100 mV shunt divide 5000 the desired full scale display with 0 1A resolution by 10000 displayed value with 100 mV when the scale factor is 1 0 for a scale factor of 0 5 For process amp strain meters scaling is normally set up from the front panel using the and A keys but can also be set up via RS232 485 using special PC compatible setup software available at no charge The meter allows three scaling methods to be selected 1 Scale and offset 2 Coordinates of 2 points and 3 Reading coordinates of 2 points Only menu items applicable to the selected method will be presented DC RATIO OPERATION In the DC ratio or potentiometer follower mode the meter tracks a ratio of the applied excita tion voltage and is unaffected by changes in the excitation voltage This capability is used for resistive bridge sensors and voltage dividers such as potentiometers which track wiper posi tion To implement set to next page For bridges and potentiometers make P5 Signal Input connec
