About This Manual

This manual provides information for the HP 60503B 250-Watt Electronic Load Module. It is designed as a supplement
to the HP 6050A/6051A Multiple Input Mainframe Electronic Load Operating Manual (part number 06050-90001). Four
tables provide the following module-specific information:

Table 60503-1 lists both the specifications and supplemental characteristics of the module. Specifications indicate
warranted performance in the 25 °C ± 5 °C region of the total temperature range (0 to 55° C). Supplemental
characteristics indicate non-warranted, typical performance and are intended to provide additional information by
describing performance that has been determined by design or type testing.

Table 60503-2 lists the ranges that can be programmed in constant current, constant resistance, and constant voltage
modes. It shows the maximum and minimum programming values for each range. Refer to this table when programming
the module locally as described in chapter 4, or remotely as described in chapter 5 of the operating manual.

Table 60503-3 gives the factory default values of the module. Unless you have saved your own wake-up settings, the
module will be set to the factory default values whenever power is applied. See chapter 4 in the operating manual.

Table 60503-4 provides calibration information for the module. This information is needed to perform the annual
calibration procedure described in chapter 6 of the operating manual.

Module Installation and Operation

Except for the module-specific information in this manual, all installation, operation, and calibration instructions are
given in the Mainframe Operating Manual. The HP Electronic Load Family Programming Reference Manual (part
number 06060-90005) contains complete programming details that apply to all Electronic Load models.

Note: The following information in chapter 2 of the Mainframe Operating Manual does not apply to electronic

load modules with the serial numbers listed on the title page of this manual: The section titled
"Extended Power Operation", and the section titled "Extended Power Limit". Also for these modules,
change the 3-second delay referred to under "Nominal Power Limit" to 50 milliseconds.

Items Supplied

In addition to this manual, a 10-pin connector plug is also shipped with your Electronic Load module. Refer to chapter 3
in the operating manual for more information.
