Operating Information

Pen:

Hysteresis ( a property that occurs when tension is applied to an object) causes the pens to move in increments across the chart as the sensor readings change. However, the display readings are not affected by the property of hysteresis. For this reason the display provides smoother and faster readings than the pen. At any given time there may be a slight discrepancy in the positions of the pens and the readings on the display.

For visual spot checks the display is the most accurate but both are within the stated specifications of the unit (see “Specifications”).

Pens (2 pen KT6):

The blue pen has a longer pen arm than the red pen. The pens are offset to allow the red pen to glide under the blue pen. The blue pen indicates the correct time and the red pen precedes it by 3/16 of an inch.

Power Supply:

We recommend using AC Power with one 9V battery installed as a back-up power source. This ensures that your recording will not be interrupted when there is a power failure. The AC Adapter is built into the back of the recorder. NOTE: When the unit is in battery back-up mode, the recorder will update temperature readings at a much slower rate. The battery should be replaced once a year and after power failures of more than a few hours.

To Replace Battery:

1.Open the door of the recorder by depressing the door latch.

2.Press the “HOME” key

3.Lift the chart, if there is one present, to fully expose the battery compartment and press down on the tab to release battery compartment door.

4.Replace 9V battery

Alarm Relays

The SPST 24V 500mA relay contacts are normally open and will close on alarm conditions when the alarms are enabled. Relay contacts are always functional when the alarm is enabled. Dip Switch #8 has no effect on the relay. The relay will close only during minimum and maximum alarm conditions. 2 pen units have two sets of relay contacts which operate independently.

NOTE: For compliance to CE directives, do not remove the rubber cover from the alarm relay terminals when the terminals are not used.
