SLM-Series AC/DC Electronic Load Operation
M540072-01 Rev B 3-5
17 Vsense BNC, Voltage Sensing Input BNC Connector.
To solve the conductor voltage drop under a big load current, Vsense-CLIP cable can be
used to connect with the specific point to be measured thus obtaining the specific voltage
value.
The control keys are summarized in Figure 3-2.

3.2 SET-UP PROCEDURES
The following set up procedures are summarized in the flow chart in Figure 3-4.
3.2.1 Pass / Fail Limits, Go/No GO Limits
(If pass/fail limits are not desired, skip to Frequency Setting below).
The limits set the value range within which the inputs must fall for the NG LED to
remain off and sets the NG register to 0 (pass) or 1 (fail).
Voltage:
Press the LIMIT key until the LIMIT LED is on and the “Vrms” LED (5) is lit. The
upper digital meter (DM) displays the upper voltage limit; the lower DM displays
the lower voltage limit. Use the coarse
 keys to set the upper limit and the
fine ↑↓ keys to set the lower limit.
Current:
Press the LIMIT key until the LIMIT LED is on and the “Arms” LED (5) is lit. The
upper DM displays the upper current limit; the lower 5-digit display shows the
lower current limit. Use the coarse  keys to set the upper limit and the fine
↑↓ keys to set the lower limit.
