In this example, the display will appear as shown below. Figure 5-4 If the H/X were reversed, the instrument will display the following error message and terminate the test. Figure 5-5 NOTE: „ If there were a polarity reversal, the Ratio would be displayed negative and it would be blinking. This means either the con- nections are reversed on a given side or the transformer is wound backwards relative to the marking. -
Page 22: Vt/Pt Excitation Current
5.2.3. VT/PT ExCITATION CURRENT Excitation current, displayed in milli-amperes (mA) is the RMS current in the Primary (H) winding due to test excitation. The load- ing on the Secondary (X) winding due to the DTR 8510 is negligible. ® „ The DTR 8510 uses a maximum of 32 Vrms excitation voltage for testing. -

Page 37: Cleaning
The smart charger has the following features: „ Multiple charge detection methods -dV (typical) and dT/dt. Typically, the indication that the battery is fully charged is detected by a slight drop in its voltage (-dV). However, if the batteries are unused for a long time, they may display the same drop in voltage in the early part of the charge cycle even if they are not fully charged. -
