SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation, service,
and repair of this instrument. Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture, and intended use of
the instrument. PRODIGIT assumes no liability for the customer's failure to comply with these
requirements.
GENERAL
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The
protective features of this product may be impaired if it is used in a manner not specified in the
operation instructions.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category I, pollution degree
environments. It is designed to operate at a maximum relative humidity of 80% and at altitudes of
up to 000 meters. Refer to the specifications tables for the ac mains voltage requirements and
ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage and the correct fuse is installed.
GROUND THE INSTRUMENT
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To
minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical
ground. The instrument must be connected to the ac power supply mains through a three
conductor
power cable, with the third wire firmly connected to an electrical ground (safety ground) at the
power outlet. Any interruption of the protective (grounding) conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that could result in personal injury.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay,
etc.) should be used. Do not use repaired
Fuses or short circuited fuse holder. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal
adjustments must be made by qualified service personnel. Do not replace components with power
cable connected. Under certain conditions, dangerous voltages may exist even with the power
cable removed. To avoid injuries, always disconnect power, discharge circuits and remove
external voltage sources before touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid
and resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference and must
be connected to a properly grounded receptacle to minimize electric shock hazard. Operation at
line voltages or frequencies in excess of those stated on the data plate may cause leakage
currents in excess of 5.0 mA peak.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or perform
any unauthorized modification to the instrument. Return the instrument to a PRODIGIT
ELECTRONICS Sales and Service Office for service and repair to ensure that safety features are
maintained.
Instruments which appear damaged or defective should be made inoperative and secured against
unintended operation until they can be repaired by qualified service personnel.

The load current level and load status are can be set with Front panel on each module, GPIB
command. It is called manual operation and GPIB operation respectively, the load input
voltage and load current can be read back to computer through GPIB.
The GPIB operation is described in Chapter 4 GPIB operation.
Slew Rate:
Slew rate is defined as the change in current or voltage over time. A programmable slew rate
allows a controlled transition from one load setting to another to minimize induced voltage
drops on inductive power wiring, or to control induced transients on a test device (such as
would occur during power supply transient response testing).
In cases where the transition from one setting to another is large, the actual transition time can
be Calculated by dividing the voltage or current transition by the slew rate. The actual transition
time is Defined as the time required for the input to change from 10% to 90% or from 90% to
10% of the Programmed excursion. In cases where the transition from one setting to another is
small, the small Signal bandwidth of the load limits the minimum transition time for all
programmable slew rates. Because Of this limitation, the actual transition time is longer than
the expected time based on the slew rate, as Shown in Figure 1-1
Therefore, both minimum transition time and slew rate must be considered when determining
the actual transition time.
The minimum transition time for a given slew rate as about a 30% or greater load change, the
slew rate increases from the minimum transition time to the Maximum transition time at a 100%
load change. The actual transition time will be either the minimum transition time, or the total
slew time (transition divided by slew rate), whichever is longer.
Use the following formula to calculate the minimum transition time for a given slew rate
Min transition time = 36/slew rate (in amps/second)(7. us(36/5)*0.8(10%~90%)=5.76uS)
Use the following formula to calculate the maximum transition time for a given slew rate
Max transition time = 1 0/slew rate (in amps/second) ( 4us(1 0/5)*0.8(10%~90%)=19. uS)
EX. CCH= 4A, CCL=0A Slew Rate = 5A, The expected time is 3.84uS but the actual transition
time will be limited to 5.76uS((36/5)x0.8 )
