Optional Hardware and Software Model GFC7001E Carbon Dioxide Analyzer
Teledyne Analytical Instruments 62
5.3. CARRYING STRAP/HANDLE (OPT 29)
The chassis of the GFC 7001E/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”).

Installing the strap handle prevents the use of the rack mount slides, although the rack mount brackets, Option
21, can still be used.
CAUTION
GENERAL SAFETY HAZARD
A fully configured GFC 7001E/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.
