Operation Description Elgar Electronics Corporation
1.1.1 NAVIGATION AND SETTING
1. Press CHAN key to select channel (A or B) to be calibrated (each
channel is calibrated separately).
2. Press MODE and LIMIT keys simultaneously to enter calibration
mode (Constant Current is default initial mode).
3. Press key to return to previous item (parameter); press to
advance to next item
NOTE: There are 18 items (parameters) to calibrate.
4. Load level and status are set to default value automatically at each
step.
5. Press keys to adjust the calibration values.
6. Press DUAL V/A key to store the calibration data.
7. Press LIMIT key to exit calibration mode.
Refer to
Figure 1-2 for a flowchart of the calibration procedure.

CALIBRATION PROCEDURE
2.1 CALIBRATION SETUP
Prior to starting the calibration procedure, gather the necessary equipment
(Section
minutes.
2.1.1 EQUIPMENT REQUIRED
2.1.1), then power up the chassis and allow it to warm up for 15
Voltage/Current Source/Calibrator: Krohn-Hite EDC 521.
Current Shunt: Prodigit 7550.
Digital Multi-meter (DMM): Agilent 34401A.
DC Power Supply: SGA80-125. (Supply may depend upon models
being calibrated. This model covers any module in the SLD
family.)
SECTION 2
Current Probe: Tektronix A6303.
2.2 CHANNEL A CALIBRATION
Press CHAN key to light the A LED.
Press both MODE and LIMIT keys simultaneously to enter calibration mode.
Initial default mode is Constant Current (CC) Mode.

1. Set DC power supply to +5VDC.
2. PRES ON (press PRES key until its LED is lit); set load current setting
to match the value shown in Load Setting column of
model being calibrated.
3. LOAD ON (press LOAD key until its LED is lit); adjust using the
keys until the DMM reading matches the value shown in DMM
Reading column
