    1529 remotely. 5.1 Display The 1529 display consists of two parts. The top portion of the display is used for displaying the measurements from one to four inputs. The bottom portion of the dis- play is reserved for the programmable fields and field display sets. Information about the channels and measurements can be displayed in greater detail such as min, max, spread, standard deviation, and many other functions.

  • Page 28: Probe Input Modules

    The battery pack can be easily removed and replaced in the field by following this procedure: 1. Power the 1529 off and unplug the AC adapter from the unit. 2. Turn the 1529 over to expose the battery compartment. Remove the battery cover hex screw.

  • Page 29: Figure 4 Probe Connection Wiring Diagram

    General Operation Probe Input Modules When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as stated in the specifications. Compensation is made for 3-wire PRTs, but the difference in lead resistance affects the measurement accuracy. The 1529 thermometer readout is unable to compensate for 2-wire lead resistance.

  • Page 30: Connecting A Thermocouple

    The DC power source provides power to charge the battery. It can also be used to pow- er the 1529 while the battery is being charged. The AC adapter provided with the 1529 is intended for these purposes. The DC power source plugs into the DC power input on the back panel of the instrument.

    Taking Measurements 5.6 Power On Self-Test When power is turned on, the 1529 performs a self-test checking the system, all chan- nels, calibration, GPIB, memory, and buttons. If an error occurs, an error message is displayed. See Section 10.1, Troubleshooting on page 125 for additional information on error messages.
