Section 1: Introduction 

 
This section includes a Quick Start procedure, photos of a typical MicroCAT 
shipment, and battery shipping precautions. 
 
 

About this Manual 

 
This manual is to be used with the SBE 37-SM MicroCAT Conductivity and 
Temperature Recorder (pressure optional) with 

RS-232

 interface. It is 

organized to guide the user from installation through operation and data 
collection. We’ve included detailed specifications, command descriptions, 
maintenance and calibration information, and helpful notes throughout  
the manual. 
 
Sea-Bird welcomes suggestions for new features and enhancements of our 
products and/or documentation. Please contact us with any comments or 
suggestions ([email protected] or 425-643-9866). Our business hours are 
Monday through Friday, 0800 to 1700 Pacific Standard Time (1600 to 0100 
Universal Time) in winter and 0800 to 1700 Pacific Daylight Time (1500 to 
0000 Universal Time) the rest of the year. 
 
 

Quick Start 

 
Follow these steps to get a

 

Quick Start using the MicroCAT.  

The manual provides step-by-step details for performing each task: 
 
1.

 

Install AA lithium cells and test power and communications (

Section 3: 

Preparing MicroCAT for Deployment

). 

 
2.

 

Deploy the MicroCAT (

Section 4: Deploying and Operating MicroCAT

): 

A.

 

Install new AA lithium cells if necessary. 

B.

 

Ensure all data has been uploaded, and then send 

InitLogging

 to 

make entire memory available for recording if desired. 

C.

 

Set date and time, and establish setup and logging parameters. 

D.

 

Check status (

DS

) and calibration coefficients (

DC

) to verify setup. 

E.

 

If you will be sampling autonomously, use one of the following 
sequences to start logging: 

 

StartNow

 to start logging now, sampling every 

SampleInterval=

 seconds. 

 

StartDateTime= 

and 

StartLater

 to start logging at specified 

date and time, sampling every 

SampleInterval=

 seconds. 

F.

 

Remove protective plugs from anti-foulant device cups, and verify 
AF24173 Anti-Foulant Devices are installed. Leave protective plugs 
off for deployment. 

G.

 

Install dummy plug or cable connector, and locking sleeve. 

H.

 

Deploy MicroCAT, using Sea-Bird or customer-supplied hardware. 

I.

 

Upload data from memory.
