3) Fine and Coarse Potentiometers : Fine potentiometer is provided for fine adjustments. Coarse potentiometer is ten turn and provided for coarse adjustment. Both pots are common for mV and mA values. These multi turn pots are delicate and should be handled carefully.

	4) RTD Simulator : Instrument can be used as PT 100 RTD simulator same as decade box. Remaining positions of the rotary selector switch selects the discrete temperature values marked in dial. Resistance value of the PT 100 RTD proportional to the selected temperature will be available at the output terminals. Note that the RTD simulator is potential free & no indication is provided for resistance values. Put the power on switch (OFF) when RTD simulator is in use. To simulate three wire input take one wire from one terminal and two wires from the other terminals.
Connection as RTD Simulator


	5) Protections : mV source is protected against short circuit and mA source output is protected against over current. mV/mA sink modes are also protected, however, care must be taken not to exceed specified limits as there is a possibility of calibration change.

	6) Battery Life : Instrument is powered with two numbers of 9V 100 mAh batteries. Instrument works for six hours continuously, when current source is operating at full scale (20 mA), if current source is open and mV source is operating. Instrument can work for more than 30 hours continuously. A LOBAT appears on display when batteries are discharged.
