5.3. CARRYING STRAP/HANDLE (OPT 29) 
The chassis of the M300E/EM Analyzer allows the user to attach a strap handle for carrying the instrument.  The 
handle is located on the right side and pulls out to accommodate a hand for transport.  When pushed in, the 
handle is nearly flush with the chassis, only protruding out about 9 mm (3/8”).

M300E/EM with Carrying Strap Handle and Rack Mount Brackets 
Installing the strap handle prevents the use of the rack mount slides, although the rack mount brackets, Option 
21, can still be used.

A fully configured M300E/EM with valve options weighs about 23 kg (51 pounds). 
To avoid personal injury we recommend two persons lift and carry the analyzer. 
Ensure to disconnect all cables and tubing from the analyzer before carrying it. 
 
5.4. CURRENT LOOP ANALOG OUTPUTS (OPTION 41) 
The current loop option adds isolated, voltage-to-current conversion circuitry to the analyzer’s analog outputs. It 
converts the DC voltage analog output to a current signal with 0-20 mA output current. The outputs can be 
scaled to any set of limits within that 0-20 mA range. However, most current loop applications call for either 2-20 
mA or 4-20 mA range. All current loop outputs have a +5% over-range. Ranges with the lower limit set to more 
than 1 mA (e.g., 2-20 or 4-20 mA) also have a -5% under-range, 
This option may be ordered separately for three of the analog outputs and can be installed as a retrofit. 
Figure 5-2 provides installation instructions and illustrates a sample combination of one current output and two 
voltage outputs configuration. Section 5.4.1 provides instructions for converting current loop analog outputs to 
standard 0-to-5 VDC outputs. Information on calibrating or adjusting these outputs can be found in Section 
7.4.3.5.
