Series 2600 System SourceMeters Reference Manual
WARNING
Setting the source range and output value
Before testing each verification point, you must properly set the source range and
output value as outlined below.

Setting the measurement range
When simultaneously sourcing and measuring either voltage or current, the
measure range is coupled to the source range, and you cannot independently
control the measure range. Thus, it is not necessary for you to set the range when
testing voltage or current measurement accuracy.
The maximum common-mode voltage (voltage between LO and
chassis ground) is 250VDC. Exceeding this value may cause a
breakdown in insulation, creating a shock hazard.
The Input/Output terminals of the SourceMeters are rated for
connection to circuits rated Installation Category I only, with
transients rated less than 1500V peak. Do not connect the
Series 2600 terminals to CAT II, CAT III, or CAT IV circuits.
Connection of the SourceMeter terminals to circuits higher
than CAT I can cause damage to the equipment or expose the
operator to hazardous voltage.
Hazardous voltages may be present on the output and guard
terminals. To prevent electrical shock that could cause injury
or death, NEVER make or break connections to the Series 2600
while the unit is on. Power off the equipment from the front
panel or disconnect the main power cord from the rear of the
Series 2600 before handling cables connected to the outputs.
Putting the equipment into standby mode does not guarantee
the outputs are not powered if a hardware or software fault
occurs.
Press the SRC key to select the appropriate source function.
Press the Rotary Knob or ENTER to enable the edit mode (EDIT
annunciator on).
When the cursor in the source display field is flashing, set the source range
to the lowest possible range for the value being sourced. Use the up or
down RANGE key to set the value.
Use the Rotary Knob and CURSOR keys to set the source value to the
required value, then press ENTER or the Rotary Knob to complete editing.
