High Voltage Notes
IF YOU USE MOTIVE BATTERIES TO POWER
YOUR METER:
If the HV battery is "tapped" to provide meter power, it is recommended
that a 24V tap, not a 12V 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 Your Meter 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 per-
sonal shock hazard. Use caution in connecting wires to the DB-9 on the
rear of Your Meter as Pin #5 is connected directly to motive battery (-).
F13 SET VOLTAGE SCALING
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
Pages 21 & 22 of Owner's Manual - "Charged Parameters".
DEFAULT: 0= 0-50V. Options: 1= 0-100V, 2= 0-500V
