3. Press LIMIT to view the set current limit. The red indicator light above the button should be on, and the set limit will be shown on the LED display. To adjust the current limit, follow the procedure in Section 2.1. 4. - Page 10 8. Sponge pads can not dissipate heat as effectively as Scoth Brite ® gel pads. For high power, high intensity applications, it is advisable to use gel pads in place of sponge pads to minimize localized heating effects. 9. Do not increase voltage settings beyond those indicated in Table 1 for overnight operation. If overnight transfers at low voltages are ineffective for your application and you must increase the voltage, you must also decrease the transfer time and/or provide external cooling.
