SLH-Series AC High Power Electronic Load Operation
M540073-01 Rev C 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 Figure 3-4.
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.
Power:
Press the LIMIT key until the LIMIT LED is on and the “W” LED (5) is lit. The upper DM
displays the upper power limit; the lower DM displays the lower power limit. Use the coarse
 keys to set the upper limit and the fine ↑↓ keys to set the lower limit.
