1. INTRODUCTION

RADICAL is a precision thermometer/calibrator for measurement of process signals and calibration of process instruments.

RADICAL is a microcontroller based design. It incorporates a highly stable reference, a high-resolution Analog - to - Digitalconverter, electronic switching circuitry & other specialized electronics.

Further, use of the micro-controller allows direct display in ºC/ºF for thermocouple and RTD inputs, as well as automatic andmanual cold-junction compensation for thermocouples.

Features

Measure mV, mA, RTDs, thermocouples, ohms

Source mV, volts, mA, thermocouples, RTDs, ohms

Continuity test (in MEASURE mode)

Simulate 4 to 20 transmitter (in SOURCE mode)

Loop 24V (in measure mA)

Simultaneous Measure and Source

Step, ramp, % scale, min-max valuesNon tactile membrane keypad

24 keys with 3 Softkeys

128 x 64 graphic LCD display with backlight

Auto shutoff and LO BAT

8~14 hours of use with Lithium-ion rechargeable battery

This manual provides complete operating instructions as well as terminal connection details, for different modes of operation.

2.4 Display

Figure 3. Elements of a typical display

Figure 3 shows the features of a typical display of MEASURE mA mode. The other parts of display are as follows:

Mode Indicator: shows whether the calibrator is in MEASURE or SOURCE mode. In split screen MEASURE /SOURCE mode, there is a Mode Indicator for each window.

Measured Value: shows the measured value in your choice of engineering units or percent of scale.

2.5 Charging the Battery

The Lithium-ion Battery Module Model LB918 is charged using the Battery charger Model BC1 supplied.Normally a charging period of 4 hours is enough for a full charge.

2.6 Battery Life

Radical performance is guaranteed to meet specifications until the low battery annunciator located at the top right side of

the display appears. When the annunciator appears, stop using the radical and charge the battery. If you have a fully

charged spare battery, exchange it with the low battery.

The battery is useful for up to 250 charge/discharge cycles if used optimally.

If you need to replace the battery, refer to “7.1 Replacing the Battery Module”.

For long battery life & best performance, wait for to appear before you recharge the battery.

3. SETTING UP RADICAL

In setup mode user can set Auto off time, Beeper condition, Backlight condition at power on & Power on mode.

Auto off An optional Auto off feature turns the Radical off after a selected time if no key operation is done in this period.

Beeper This feature allow user to set beeper sound ON or OFF for key press.

Backlight at power onThis feature allows user to set power on condition for backlight (ON or OFF).

( key is used to make backlight ON or OFF after power on.)

Power on modeRadical allows user to set power on mode. e.g. if user selects Meas mA mode as power on mode then at every power onit will switch on in MEASURE mA mode.

4. 6.2 Using Resistance-Temperature Detectors (RTDs)

The calibrator supports following standard RTD Pt 100,Pt 200,Cu 53 ,Ni 120

The calibrator accepts RTD types. RTD are characterized by their resistance at 0°C which is called the “ice point”. The most

common R is 100and mostly come in a three-terminal configuration.

The calibrator accepts RTD measurement inputs in two, three or four wire connection. A four-wire configuration provides thehighest measurement precision and two wire provide the lowest measurement precision.

To measure temperature using an RTD input, proceed as follows:

5.5 Simulating a 4 to 20 mA Transmitter

You can configure the calibrator as a load on a current loop through the SOURCE mA function. The difference in operation is that,when you Source mA, the calibrator is sourcing current and when you simulate Transmitter, the calibrator is sourcing a variableresistance to regulate current to the specified value.

7. MAINTENANCE

7.1. Replacing the Battery Module

Replace the Battery Module when it no longer holds charge for an adequate duration by following the procedure given below.See 7.4 for ordering information.

1 Remove fitting nuts by turning nuts anti-clockwise.

2 Gently pullout the Battery Module.

3 Remove connector J1 from the Battery Module.

4 Connect new Battery Module to connector J1.

5 Insert Battery Module back into Radical.

6 Fix both nuts.

7.2. Cleaning the Calibrator

Clean calibrator with a soft cloth dampened with water or water & mild soap. Do not spill droplets.CAUTION : To avoid damaging the plastic lens & case, do not use solvents or abrasive cleansers.

7.3. Service Center Calibration or Repair

Calibration , repairs , or servicing not covered in this manual should be performed only at our service center. If the calibrator fails ,check the Lithium-ion battery pack first, and replace it if needed. Verify that the calibrator is being operated in accordance with theinstructions in this manual. If the calibrator is faulty, send a description of the failure with the calibrator. Be sure to pack the

calibrator securely, using the original container if it is available. Send the equipment postage paid to Service Center.
