Criterion Series Benchtop User’s Manual Introduction This manual has been written for users of the Criterion Series Chambers and particularly for technicians. Read it thoroughly to obtain the maximum performance from the chamber. Safety Symbols The following safety symbols are used throughout this manual. Degrees of Danger This mark means extremely dangerous VERY...

Precautions Accessories & Spare Parts Confirm that the following accessories and spare parts have been included with your chamber. Accessory / Part Quantity Power Cord To provide power to the chamber from an 1 Set outlet. Details of plug type are in the installation section (4) of the manual Wicks For humidity detection in humidity models,...
Precautions 1. Precautions in Usage This chapter explains safety precautions that should be observed to operate the equipment safely. Be sure to read carefully and follow instructions so as to prevent harm to yourself, anyone else, specimens, or the equipment. 1.1.
Precautions 1.3. Specimen Protection (Safety Devices) CAUTION • Set safety devices according to test conditions and the type of specimens. Unless properly set, specimens could be damaged if something goes wrong during testing. The chamber is controlled to a target constant temperature and humidity* by the temperature (& humidity) controller.
Precautions Absolute high/low limit temperature (& humidity) alarms and upper deviation limit temperature alarm. The absolute high/low limit alarms are completely independent of the target temperature and humidity. They do not change when target temperature or humidity are changed. Conversely, the upper deviation limit alarm is relative to the target temperature. If the target temperature is changed, the deviation alarm temperature changes in proportion.
Page 10
Precautions With the settings in Table 1.2., the safety devices will trip in the succession shown in Figure 1.2. as temperature inside the chamber rises beyond the target temperature. The first to trip will be the upper deviation limit alarm, followed by the absolute high limit alarm and then the overheat protector.
Precautions 1.4. Disposing of the Chamber DANGER • TRAPPED INSIDE! Before disposing of the chamber, take the door off its hinges. The door cannot be opened from the inside, so there is the danger of someone becoming trapped inside. You will need a Phillips-head screwdriver to detach the door. Procedure 1.
Precautions 1.5. Other Precautions Observe the following precautions when using the chamber. DANGER • DO NOT use or leave equipment outdoors. Not only can outdoor environments adversely affect performance and functioning, but also electrical part contact with water can lead to short-circuit, fire, electrical shock and breakdown.
1.6. Global Warming Potential of Refrigerants Refrigeration circuit contains fluorinated greenhouse gases covered by the Kyoto Protocol. See chart below for global warming potential of refrigerants used by ESPEC. See chamber serial tag for refrigerant and quantity used in this chamber.
Precautions 2. Overview This chapter gives an overview of the Criterion Series and temperature & humidity control. 2.1. About the Criterion Series Equipment, parts and the materials from which they are made are used and stored in places where temperature and humidity are much higher or lower than usual. A harsh environment can damage them.
Precautions 2.2. Temperature (& Humidity) Control and Instrumentation 2.2.1. Temperature (& Humidity) Control The Criterion Series employs a BTHC system to control temperature and humidity. “BTHC” stands for Balanced Temperature and Humidity Control. The BTHC system balances temperature and humidity inside the chamber to reproduce the desired conditions.
Criterion Series Benchtop User’s Manual 2.2.2. Watlow Instrumentation The Watlow Instrumentation enables environmental testing under both constant conditions and programmed conditions, referred to as the “constant mode” and the “program mode” respectively. Constant Mode The constant mode maintains the user-set target temperature (& humidity) constant, thus the name.

This chapter explains how to install the chamber and prepare for tests. Be sure to read the parts on installation even if having the chamber installed by the place of purchase or ESPEC. Also, refer to this chapter whenever relocating the chamber.
Criterion Series Benchtop User’s Manual 4.2. Power Supply Work 4.2.1. Primary Power Supply Requirements The primary power supply must satisfy the following requirements. • Voltage fluctuation must be within ± 5% of the rated voltage. (Within ± 10% while the chamber is running.).
Criterion Series Benchtop User’s Manual 4.2.2. Primary Power Supply Connections The chamber is connected to the primary power supply via the power cable. It is also grounded to prevent noise from infiltrating electronic circuits and to protect users against electric shock which can result from leakage current.
Criterion Series Benchtop User’s Manual 4.3. Drainage CAUTION • If collecting drainage in a container, check water level to make sure it does not overflow. Drainage is needed to drain water from the humidifier (BTX and BTL models only) and dew formed in the test area out of the chamber.
Criterion Series Benchtop User’s Manual 4.4. Humidity Water Supply (BTL and BTX models only) Removal of the Water Level Regulator Protection Material The wick pan water level regulator is contained inside the machine section, located on the rear of the chamber. Procedure 1.
Criterion Series Benchtop User’s Manual 4.4.1. Water Supply Installation Connection of the Water Supply Hose for the Humidifying Water Circuit CAUTION • Remove packing sponges from the float level cups before supplying water to the chamber. Failure to do so can cause water to overflow in the humidity system and spill water on your laboratory floor making the floor extremely slippery.
Page 30
Criterion Series Benchtop User’s Manual Reference If water level in the wick pan is low or high, regulate it as follows: 1. Stop the supply of water and drain the water from inside the pan by opening the valve below the water level regulator. 2.
