EMC Directive

Hart Scientifics' equipment has been tested to meet the European Electromag-
netic Compatibility Directive (EMC Directive, 89/336/EEC). The Declaration
of Conformity for your instrument lists the specific standards to which the unit
was tested.

Low Voltage Directive (Safety)

In order to comply with the European Low Voltage Directive (73/23/EEC),
Hart Scientific equipment has been designed to meet the IEC 1010-1 (EN
61010-1) and the IEC 1010-2-010 (EN 61010-2-010) standards.
Causes and Solutions
Too much heating or not enough cooling can cause this problem.
•
Check that the control indicator glows green showing
that the controller is attempting to cool. The heaters may
be disabled as a test by temporarily removing the heater
fuses.
Note: Before performing the memory check,you need to record the
controller calibration parameters (found in the CAL menu of the instru-
ment) and any user-adjusted parameters that you have changed (such
as the programmable set points and proportional band).
Memory Check
Doing a memory check is the easiest way to verify the ability of the
battery to maintain controller parameters.
1. Power off the instrument.
2. Disconnect the instrument from AC power for 10 seconds.
3. Reconnect the AC power and power on the instrument.
4. If the display shows InIT and/or the cycle count shows a low num-
ber such as 0002, the battery is spent and should be replaced. Con-
tact an Authorized Service Center for assistance.
5. After replacing the battery, you must reprogram the calibration and
user-adjustable parameters into the controller.
