Dry-well Calibrator

Quick Start

5

AC Power Operation

Plug the mains power cable of the Product into a mains outlet of the proper voltage, frequency, and 
current capability. Refer to 

Unpacking

 and 

Specifications

, for power details. Turn on the dry-well using 

the switch on the rear panel. The dry-well turns on and heats to the previously-programmed 
temperature set-point. The front-panel display indicates the actual dry-well temperature.

DC Power Operation

The Product has a dc power option. The dc option requires a power source that delivers 12 V dc at 3 A.

W

Warning

A fire may occur if a short circuit occurs along the input cord and no protective devices 
are on the dc input source. For short-circuit protection using a battery, a fuse is 
required at the battery terminals.

The dc power socket is on the rear panel of the Product near the ac power jack. The Product accepts a 
7/32 inch diameter, two-conductor dc power plug such as Switchcraft® PN 760. Observe the correct 
polarity as shown in Figure 

1

. The outside conductor is positive and the inside is negative. The ac 

power switch on the rear panel does not switch the dc power.

Setup

Place the Product on a flat surface with at least 6 inches of free space around the Product. Always 
leave enough clearance in front of the Product to allow for safe and easy insertion and removal of 
probes. The prop stand may be swung down to raise the front of the Product from a horizontal position. 
Plug the power cord into a grounded mains outlet. Observe that the nominal voltage corresponds to 
that indicated on the Product.
Turn on the power to the Product with the power switch. The fan begins to quietly blow air through the 
Product and the controller display illuminates after 3 seconds. After a brief self-test the Product begins 
normal operation. If the unit fails to operate, check the power connection.
The display shows the well temperature and the well heater brings the temperature of the well to the 
set-point temperature.
After Product use, allow the well to cool by setting the temperature to 25 °C and then wait  
1/2 hour before you turn off the Product.
