charger. The Model BC7217 charger charges boththe NiMH and Ni-Cd battery packs.

Figure 9 shows how to remove the battery. Removethe battery door and tap the calibrator with yourhand to get the battery out. Place the battery in thecharger and connect the charger to line power. Thecharger automatically senses line voltage and

adjusts itself accordingly.

A discharged battery is fully charged in 2 hours orless in fast-charge mode (steady indicator light on

the charger). Full charge is maintained after thattime in trickle-charge mode (blinking indicator lighton the charger). Switching between charging modes

is automatic. You can leave the battery pack on

trickle charge indefinitely without damage.

Note

When you remove a charged battery fromthe charger, wait for the blinking indicator togo off before you insert a dischargedbattery. It takes about 2 seconds for thebattery charger to reset.

Battery Life

The calibrator senses which battery is installed(standard NiMH, or optional Ni-Cd model BP 7217).

If the NiMH battery is installed, a battery gauge bargraphshows on the upper right of the display.If the Ni-Cd battery is installed, there is no batterylevel indication except for a low battery symbol,that appears when it is time to charge the battery.

Table 4 shows the typical operating time for a new,fully charged NiMH (Nickel-Metal Hydride) battery

pack. The optional Ni-Cd battery (Model BP7217)

provides approximately half the battery life of the

NiMH battery. Calibrator performance is guaranteedto meet specifications until the battery gauge readsempty (or).

To replace the battery, refer to Replacing theBattery later in this manual for instructions. In thecase of the Ni-Cd battery, for longest battery life andbest performance, wait forto appear before youcharge the battery.

Supplying Loop Power

The calibrator supplies loop power at 28 V or 24 V dcthrough an internal series resistance of 250 . The28 V setting supplies enough current for two or three

4-20 mA devices on the loop in addition to the two-wire transmitter but uses more battery power. Usethe 24 V setting if there are two or fewer devices onthe loop in addition to the two-wire transmitter. (Eachdevice on a typical 4- to 20-mA loop has a resistanceof 250, thus dropping 5 V at 20 mA. A typicaltransmitter must have 11 V minimum in order to

operate correctly at its top end.)

When loop power is enabled, the mA (middlecolumn) jacks are dedicated to sourcing andmeasuring the current loop. This means that theSOURCE mA, measure RTD, and measure functions are not available (see Table 8, later in thismanual.)

Connect the calibrator in series with the instrumentcurrent loop as Figure 18 shows. Proceed as follows

to source loop power:

1. Pressfor Setup mode.

2. Note that following Loop Power, Disabledishighlighted. Press.

3. Use theorarrow keys to select Enabled 24Vor Enabled 28 V.

Sourcing Pressure

The calibrator provides a source pressure displayfunction that requires the use of an external pressure

hand pump. Use this function to calibrate instruments

that require a pressure source or differential pressuremeasurement. See Figures 19 and 34 for informationabout that application.

Many ranges and types of pressure modules areavailable from Fluke. See Accessories near theback of this manual. Before you use a pressure

module, read its Instruction Sheet. The modules varyin how you use them, how you zero them, what types

of process pressure media are allowed, andaccuracy specification.

To use the source pressure display, see Figure 19and proceed as follows:

Warning

To avoid a violent release of pressure ina pressurized system, shut off the valve

and slowly bleed off the pressure beforeyou attach the pressure module to thepressure line.

Caution

To avoid mechanically damaging the

pressure module, never apply more than10 ft.-lb. of torque between the pressure

module fittings or between the fittingsand the body of the module. Alwaysapply appropriate torque between thepressure module fitting and connectingfittings or adapters.

To avoid damaging the pressure modulefrom overpressure, never apply pressureabove the rated maximum printed on thepressure module.

To avoid damaging the pressure modulefrom corrosion, use it only with specifiedmaterials. Refer to the printing on thepressure module or the pressure module

instruction sheet for the acceptablematerial compatibility.

Ramping the Output Proceed as follows to ramp (i.e., sweep the source):

8/12/2019 744 manual

71/135

62

Ramping sweeps the source up or down in value.Use the ramp feature to check a limit switch or alarm,or any time you want a smoothly increasing or

decreasing output function. You can set thecalibrator to ramp up or down in engineering units(mV, V, mA, C, etc.) or % of scale.

During ramping, the output is adjusted 4 times persecond. The size of the steps is determined by yourchoices of endpoints and ramp time. For example, ifyou set the calibrator to ramp from 1 mV to 1 V over

10 seconds, the output is adjusted in approximately

25 mV steps.

Ramping continues until the selected limit is reached,or until an optional trip condition is encountered. Theoptional trip detect works as follows: during ramping,the calibrator checks for either a 1 V change in dcvoltage or a change in continuity status (Openor

Short) from one second interval to the next.

1. Refer to the appropriate heading earlier in thismanual (e.g., Sourcing Electrical Parameters)and connect the calibrator to the circuit to be

tested. Figure 22 shows an example.

2. To automatically stop ramping if a trip conditionis detected, connect a voltage trip circuit to the VMEAS jacks or a continuity trip circuit to the mARTD MEAS jacks. (Continuity detection is notavailable when sourcing current.)


4. Set the calibrator for the desired source value aspreviously described.
