AMETEK SLH Series RevC - Manual (Page 35)

Sorensen SLH-Series DC High Power Electronic Load Operation
◦ Test Mode: Normal, OCP, OPP
◦ returns to OFF and the loop repeats
• The LED indicates whether limits are being programmed or not:
◦ LED lit = ON
◦ LED not lit = OFF
13 Coarse/Fine Adjust, Increment/Decrement Keys
These keys are used in two different ways, depending on the value(s) being displayed:
• When only one value is displayed, such as for setting Load On voltage, these keys are
for coarse and fine adjustments:
◦ The coarse-adjust keys (larger arrows, × Ø) increase or decrease the setting
values by larger increments.
◦ The fine-adjust keys (smaller arrows, ↑↓) increase or decrease the setting
values by smaller increments.
• When two values are displayed (one in upper 5-character display and one in lower 5-
character display), such as for setting upper and lower limits, these keys are for
increment/decrement changes:
◦ The larger arrows, × Ø, increase or decrease the setting value in the upper 5-
character display.
◦ The smaller arrows, ↑↓, increase or decrease the setting value in the lower 5-
character display.
Table 3-1 contains the detailed step resolution of each range for each SLH-series DC series
load module.
14 T HIGH / T LOW PERIOD Keys and LEDs
• The T HIGH and T LOW keys are used to program the duration of high and low load
current levels, respectively.
• The LEDs indicate which time period (T HIGH or T LOW) is being programmed.
15 RISE / FALL SLEW RATE Keys and LEDs
• The Rise and Fall keys are used to program the speed of load current changes from
low level to high level (Rise) and from high level to low level (Fall).
• The LEDs indicate which slew rate (Rise or Fall) is being programmed.
16 HI / Lo LEVEL Keys and LEDs
• These two keys are used to program the High and Low loads for current, resistance,
voltage, or power, depending on which mode is set (CC, CR, CV, or CP). (Follow
guidelines in the Operation-Setup section that follows).
• The LEDs indicate which level (HI or Lo) is being programmed.
