HD2102 - 3 - V2.3

INTRODUCTION

The HD2102.1 and HD2102.2 are portable instruments with a large LCD display. They measure

illumination, luminance, PAR and irradiance (across VIS-NIR, UVA, UVB and UVC spectral

regions or in the measurement of effective irradiance according to the UV action curve).

The probes are fitted with the SICRAM automatic detection module: in addition to detection, the

unit of measurement selection is also automatic. The factory calibration settings are already

memorized inside the instruments.

In addition to instantaneous measurement the instruments calculate the acquired measurements time

integral Q(t). Some thresholds can be associated with the integrated measurement and with the

integration time, which can be set in the menu. When exceeded these thresholds cause the

instrument to stop the integral calculation.

The HD2102.2 instrument is a datalogger. It memorizes up to 38,000 samples with single probes

and 14,000 with combined probes. Data can be transferred from the instrument connected to a PC

via the RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can be

configured using the menu.

The HD2102.1 and HD2102.2 models are fitted with an RS232C serial port and can transfer the

acquired measurements in real time to a PC or to a portable printer.

The Max, Min and Avg function calculate the maximum, minimum or average values.

Other functions include: the relative measurement REL, the HOLD function, and the automatic

turning off that can also be disabled.

The instruments have IP66 protection degree.

This manual describes the HD2102.1 and HD2102.2 models: if not otherwise specified, the

description is intended to be applicable to both models.

KEYBOARD AND MENU DESCRIPTION

Foreword

The instrument keyboard is composed of single-function keys, like the SERIAL key in the

HD2102.1 model, and double-function keys such as the ON-OFF/Auto-OFF key.

In the double-keys, the function in the upper part is the “main function”, while the one in the bottom

part is the “secondary function”. When the instrument is in standard measurement mode, the main

function is active. In the menu or in conjunction with the FUNC key, the secondary function is

enabled.

The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the

wrong key is pressed.

Each key specific function is described in detail below.

ON-OFF/Auto-OFF key

The instrument is turned on and off using the ON/OFF key. The turning on enables all display

segments for a few seconds, starts an auto-test including the detection of the probe connected to the

input, and sets the instrument ready for normal measurement.

MIN

min s

>>>

If during turning on no probes are connected, the message PROB ERR is displayed.

When the probe is inserted into a functioning instrument, it is not detected. As the probe's

data are captured upon turning the instrument on, it is necessary to turn the instrument off

and on again.

Replace the probes when the instrument is off.

If a combined probe LP 471 P-A or LP 471 A-UVeff is connected to the instrument, at switching on,

the instrument displays alternatively the measures of the two sensors. Pressing any key (excluded

ON/OFF key), automatic commutation is turned off. To reactivate it, press HOLD and REL keys

together.

Automatic turning off

The instrument has an AutoPowerOff function that automatically turns the instrument off after about

8 minutes if no key is pressed during the intervening time. The AutoPowerOff function can be

disabled by holding the HOLD key pressed down during the entire turning on phase: the battery

symbol will blink to remind the user that the instrument can only be turned off by pressing the

<ON/OFF> key.

HD2102 - 9 - V2.3

The automatic turning off function is disabled when external power is used. On the other

hand, it cannot be disabled when the batteries are discharged.

FUNC/ENTER key

During normal measurement this enables the display and logging of the maximum (MAX),

minimum (MIN) and average (AVG) value of the measurements captured by the probe connected to

the instrument, updating them with the acquisition of new samples. The acquisition frequency is

once a second.

The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even

after exiting the calculation function. To reset the previous values and restart with a new

measurement session, press FUNC until the message “FUNC CLR” appears, then use the arrows to

select YES and confirm using ENTER.

In the menu, the ENTER key confirms the current parameter and then goes to the next one.

Pressed together with the UNIT-Q/T key, enables the integral Q(t) calculation function.

Pressed together with the MENU-Clear Q/T, resets the previous integral Q(t) calculation (please see

the description of the UNIT key).

Attention: the data captured using the Record function cannot be transferred to the PC.

HOLD/key

It increases the current parameter when used in the menu; when used in measurement mode, it

freezes the measurement in progress at the current value, the message HOLD appears in the upper

side of the display. To return to the standard measurement, press the key again.

Upon turning on the instrument, the AutoPowerOff function can be disabled by holding the HOLD

key down (please see the ON-OFF key description).

During calculation of the integral Q(t), by pressing the key the displayed value is frozen without

suspending the calculation in progress.

UNIT - Q/T key

During measurement and integral Q(t) calculation, it allows selection of the unit of measurement.

By repeatedly pressing the UNIT key, the desired unit of measurement can be selected. In the

combined probes LP 471 P-A and LP 471 A-UVeff, the key allows to select one of the available

measures (in these probes, unit of measurement cannot be changed).

NOTE: The units of measurement are determined according to the probe connected to the input,

as reported in the following table:

HD2102 - 10 - V2.3

Type of measurement Unit of

Measurement

Integral Q Unit

of Measurement

Illuminance (PHOT) lux - fcd lux⋅s - fcd⋅s

Irradiance (RAD - UVA - UVB - UVC - PYRA) W/m2- μW/cm2J/m2- μJ/cm2

PAR μmol/(m2⋅s) μmol/m2

Luminance (LUM 2) cd/m2----

Note: for the LP471 LUM 2 luminance probe, the integral calculation is not provided.

This setting changes the information displayed and the immediate print of data (SERIAL key). The

data recorded using the LOG function (HD2102.2) and sent to the printer or PC through the

serial port using the SERIAL function (HD2102.1 and HD2102.2), keep the chosen and

displayed unit of measurement.

While setting the limits for Q(t) calculation, the UNIT key selects the coefficient 3, 6 and 9 that

multiplies the displayed value respectively by 103, 106, 109.

Integral Q(t) calculation

Pressing the FUNC and UNIT keys simultaneously, the integral Q(t) function is started. By pressing

the same keys again allows the current function to be exited and to return to standard measurement.

Please see the paragraph dedicated to calculation on page 17.

Start/Stop Q/T - ESC key

Starts and ends the Integral Q(t) calculation. The instrument must have previously been set for the

calculation by pressing at the same time the FUNC/ENTER and UNIT-Q/T keys.

When used in the menu, it clears or cancels the active function.

REL/key

In measurement mode, it displays the difference between the current value and that measured on

pressing the key. The REL message appears on the display; press the key again to return to the

current measurement.

When used in the menu, it decreases the current variable value.
