High Voltage Notes

HOW TO SET VOLTAGE SCALING WHEN USING A HIGH VOLTAGE PRESCALER

F13 SETVOLTAGESCALING

Sets proper voltage scaling when used with an external Voltage Prescaler. NOTE: If you use a Prescaler, you need to change the Charged Voltage to an appropriate value for your application. See "Charged Parameters" on pages 22 and 23.

DEFAULT: 0= 0–50 V. Options: 1= 0–100 V, 2= 0–500 V

IF YOU USE MOTIVE BATTERIES TO POWER THE LINK 10:

If the HV battery is "tapped" to provide meter power, it is recommended that a 24 V tap, not a 12 V tap, be used. The reason for this is that under heavy acceleration under low battery conditions, voltage may fall to levels low enough to cause the meter display to turn off momentarily. Under extreme circumstances, historical data may also be lost.

AVOID DATA LINE SHOCK HAZARD:

If you have a floating ground system and the Link 10 is equipped with the RS-232 Serial Computer Port option and is being used to record data into a laptop computer, we strongly recommend use of an optical isolator such as Omega Cat #268 to eliminate danger of a HV short to ground or personal shock hazard. Use caution in connecting wires to the DB-9 on the rear of the Link 10 as Pin #5 is connected directly to motive battery (-).
