SECTION 3 GETTING STARTED 3.1 Main Board Power Jumpers Caution: The meter has no power-on switch, so it will be in operation as soon you apply power. The meter can be configured to operate on 115VAC or 230VAC by the proper combination of the soldered wire jumpers that are located on the printed circuit board. The meter is set at the factory to be powered by the voltage specified at the time of ordering. The same transformer is used for either configuration, so all you need to do is to select

DISPLAY 3.2 Changing the Meter Parameters The proper combinations of jumper plugs S1, S2, S3, S4, and S5 inside the meter allow you to change various parameters of the meter. These parameters include resolution, range, units, RTD sensor configuration and sensor break configuration. You can change the parameters by moving the plugs on one or several of the jumper locations. Keep in mind that the meter is factory set for 3-wire RTD, and for the upscale position. Figure 3-2 shows the location of t
