17 Input On/Off Electr onic loa d's input can be toggl e d on/off at t he f r o nt panel . Turning the input off (zero curr ent) does not a ff ect the prog rammed se ttings. Th e input w ill retu rn to the previo usly pro grammed values when the input is tu rned on aga in.
18 W h en working in CR , CC and CP mode, input current is ascending continuously, the load current will be limited b y a current limit circu it, Load will wo rk in the over current p rotection state , VFD display the informatio n as CC.
19 TRIG : A TTL-compatibl e in p ut that respon d s to e x ternal edge tr igger signal. A trigger applied to this input ca n be used to change setti ngs (voltage, curr en t, r e si stance, etc.) , toggle between settin g s i n trans ient-toggle mode, or generate a pulse i n transi ent-pulse mode.
20 Battery Test ing A DC load is well suited to verify that a battery is working pro p erly. Only with the corr ect lo ad testing, the battery c an be confirm ed if it was being the expectant lif e curve locati on. The electronic loads can be us ed to test any type of battery.
21 Battery Voltage Min volt age Load Sink Curr ent V t I t Von/Voff Operatio n You can set voltage value Von/Voff to control the input state on/off for elec tronic load. W hen the input volta ge r e aches the Von value, th e load ’s i nput state is on.
22 Installation Inspect ion Damage W hen you receive your electronic load, inspect it for any obvious damage that may have oc curred during shipm en t. If there is damag e , notify th e sh i pp i ng carrier and nearest Agent offic e and Support Office immediat e ly.
23 Outline Diagram Unit (mm) Bench Operat ion A fan cools the electr on ic load by drawing air through the button and si des and exhausting it out the back . Minimum clearances for bench operatio n are 25 mm along t he si de s. CA UTI ON Do not block the fan exh a ust a t th e rear of the Load.
24 Trigger and Remote Sensi ng Connect ions A 4-pin connector and a quick-disconnect mati ng p lug ar e provided on rear panel for acces sing input signals and remote sensi ng, all leads connected to the connect or should be twisted an d shiel ded to mai nta i n the instrument's specifi ed pe rf o r mance.
