Using the Volts adjustment knob
(1), select the operating voltage
limit by turning the knob until
the desired value appears on
the Volts display (3).
Rotating the knob slowly in
the clockwise direction will
increase the displayed value
in one–volt increments.
Rotating the knob slowly in the
counterclockwise (anticlock-
wise) direction will reduce the
displayed value in the same
manner. Rotating the same
knob (1) rapidly in either
direction will cause the
displayed value to change in
ten–volt increments.
5.
Using the Milliamps Adjustment
knob (6) and Watts Adjustment
knob (9), select the desired
operating limits for milliamps
and watts, respectively. The
method used to select these val-
ues is the same as that used to
select the operating voltage
limit.

WARNING:
This power supply is capable of producing output levels well in
excess of the maximum safe operating limits for most electrophoretic chambers. For
this reason, it is important to determine the safe operating limits for milliamps and
watts. The section entitled “Choosing Safe Operating limits” has been included to
guide the user in selecting proper operating limits. This section details both the
method and rationale used in selecting these operating limits.

WARNING
This power supply is not equipped with
any user serviceable parts.
Erratic Operation:
Unstable, erratic displays, inoperable timer and/or
adjustment knobs are all possible symptoms of corrupted memory. To clear
this condition turn off the power supply, depress and hold any key and turn
the power supply back on before releasing the key.
Ground Leakage:
Ground leakage is the interconnection of earth ground
and either high voltage output. This interconnection will defeat the primary
operator safety feature of this power supply. Do not operate the power supply
when this condition exists. For further assistance, call the telephone number
listed in the service section or contact your local distributor.
