Using Menu

To enter into the menu mode, Press the ENT key. Display will show PASSand asking for password..

Press SEL key to enter password. Display will show 0000.

Now press SEL key to edit password. Now last digit will start blinking.

Now edit password digit by INC (ESC). In this case pressing SEL(SHIFT) key will shift the blinking to the next digit.

Press ENT key to give password.o If password is correct, then display will be steady instead of

blinking. Press ENT key to enter in menu mode.

o If password is wrong then unit will directly enter in RUN mode.

Scroll through the menu options using the ENT Key Conf , Cal

and Ver1.

Select the option by pressing the SEL key.

Scroll the sub menu options using ENT key.

Select the particular option by pressing the SEL key.

Use the ESC key to exit from the submenu, back to the parent menu levels.

To change the displayed value, press the SEL key again.

Now according to the option selected,o If its a text message the whole display blinks togethero Else if its a numeric value the first digit starts blink. In this case

pressing SEL (SHIFT) key will shift the blinking to the next digit.

Change the display settings using INC (ESC) key and SHIFT (SEL) key.

Press the ENT key to save the setting.

Press the ESC key and you will be in the parent menu option.

Calibration Procedure

Calibration for the unit is to be carried out by an experiencedengineer only. Reference used for the calibration should be ofhigh accuracy (0.1% better) and good stability.

After Giving correct Password Press the Enter Key to enter intothe menu levels (Scroll along using the Enter Key itself. From itselect CAL using the SELECT Key).Here we have 3 optionsAmb, INP, and OUT. Scroll along using the Enter Key andselect the required option using the SELECT Key.

Ambient Calibration:

Once you enter the ambient calibration option the ambienttemperature sensed by the device is shown. Now to calibrate itpress the Select Key that blinks the digits one by one on eachpress, use the Increment Key to change the value from 0-9.Adjust the values as required and press the Enter Key to save

the value.Exit from the menu levels using the Inc/Esc Key. Now wehave both Input and output calibration.

Input Calibration:

Here calibration is done only after entering span value(ForRTD Zero & Span value sequentially). For this we require asource with good stability and resolution.

Any of the inputs can be calibrated at any point within theentered range. The Inputs are divided into Six groups.Calibrating any of the inputs of a group will calibrate all theother inputs of the same group.The groups are:

Group0: ETC, JTC, KTC, TTC, NTC, and 0-100mV.

Group1: BTC, RTC, STC, -10 - 20mV.

Group2: RTD.

Group3: 0-5V, 1-5V.

Group4: 0-2V, 0.4-2V,0-20mA, 4-20mA.

Group5: 0-10V.

Now select the INP from the menu feed the Zero inputvalue for zero calibration (For RTD only) and enter the Zerocalibration option using the Select Key. Now change the valuesas required using the select and Inc Key. Save the value usingthe Enter Key and Exit one level back using the Inc/Esc Key.

Scroll to the Span calibration using the Enter key, PressSelect Key to enter into the span calibration. Feed the spaninput for calibration and change the values as required andpress Enter to perform calibration, Here it show a WaitMessage until it completes the calibration Procedure. It

automatically saves and applies the calibration parametersnow. Exit the menu level using the Inc/Esc Key. (There is noneed for repetition of calibration except RTD inputs)

Output Calibration

Here calibration is done only after entering both the zeroand span values sequentially for separate channels. For this werequire a DMM of 6 1/2 Digit or more resolution. No input isrequired while calibration.

Here calibration has to be done in both current andvoltage of both channels separately. Here in the menu we firstselect the channel we are calibrating, monitor the output of thatcorresponding channel using the DMM(Digital Multi meter).Here both channels have separate voltage and currentterminals. Enter the zero option and correct the value you seeon the display with the value you see in the DMM. Do the same

for the Span also. Now select channel 2 and monitor the output

of second channel and repeat what we did with the first channeloutput.

Its recommended to calibrate 0-20mA for current

and 0-10V for voltage output.
