1.1 MC-83 Display and Controls

Page 5

¬Display

Custom Liquid Crystal Display, shows Relative Humidity &

Temperature simultaneously. Indicators show the current mode.

-On / Off Switch ( ).

Press to switch the MC-83 on. Press a second time to switch the unit

back off. Alternatively, the MC-83 will switch itself off if no button has

been pressed for 10 minutes.

®HOLD

Press to freeze a reading on the display. “D.H” is shown on the

display whilst in Data Hold mode. Press a second time to un-freeze

the display. This feature is useful in rapidly changing environments

(see section 3).

¯oC / oF

Selects either OCelsius or OFahrenheit units in Temperature readout

mode. The display shows “OC” or “OF” accordingly. See section 2.

°RECORD

Press to start recording Maximum, Minimum and Average values.

Press a second time to stop recording these values. See section 4for

a full description of this function.

±RECALL

Press to sequentially recall Maximum, Minimum and Average values

recorded using the Record function. See section 4for a full

description of this function.

²Relative Humidity & Temperature Probe

The Relative Humidity & Temperature Sensor is conveniently

supplied with 1 metre of cable. The humidity sensor is a high

precision thin-film capacitance type for fast response. The thermistor

type temperature sensor is also designed for fast response in air.

³Sensor INPUT socket.

Plug the sensor into this socket. Take care to align the plug correctly

with the socket.

´Battery Compartment / Cover

Undo the retaining screw and slide out the cover to access the

battery.

2. Relative Humidity and Temperature Measurement

1. Plug the sensor into the INPUT socket. Take care to align the plug

correctly with the socket.

2. Press the green Power switch ( ) to switch the MC-83 on.

3. The Relative Humidity reading is the larger reading in the top half of

the display. Note the “% RH” indicator on the display.

The Temperature reading is the smaller reading in the bottom half of

the display. Note the “OC” or “OF” indicator on the display. Press the

“OC/OF” button to change between OCor OFreadout.

3. Freezing the Reading on the Display

When taking measurements in a rapidly changing environment, or in a

difficult to reach areas, the operator is able to freeze the display. This

allows readings to be correctly noted.

1. To freeze the display, press the “HOLD” button during normal

measurement. Note the “D.H” indicator on the display whilst the unit is

in data hold mode.

2. To resume normal measurement, press the “HOLD” button a second

time.

4. Data Record and Recall Functions

The Data Record function records the Maximum, Minimum and Average

Relative Humidity and Temperature data. This function operates as

follows…

1. Press the “RECORD“ button. Note the “REC” indicator on the display

whilst the MC-83 is in data record mode. The unit is now recording

Maximum, Minimum and Average Relative Humidity and Temperature

values.

2. While the MC-83 is still in data record mode, press the “RECALL“

button. The Maximum values will now be displayed. Note the “Max”

indicator on the display.

Press the “RECALL” button a second time. The Minimum values will

now be displayed. Note the “Min” indicator on the display.

Press the “RECALL” button a third time. The Average values will now

be displayed. Note the “AVG” indicator on the display.

Press the “RECALL” button a fourth time to return to normal Data

Record mode with current readings on the display.

3. Press the “RECORD” button any time to exit Data Record mode.

Notes

1. The automatic power off function is disabled while Data Record mode

is active.

5. Battery Replacement

1. When the battery is low the display shows “LBT” in the top left hand

corner. When this occurs the battery must be replaced as soon as

possible, otherwise readings will become inaccurate.

2. Remove the battery cover screw on the rear of the MC-83 and slide out

the battery cover.

3. Remove the battery and replace it with a new 9V battery. Alkaline

batteries are preferred.

4. Replace the battery cover and re-tighten the screw.

6. Display Mode Indicators

Below is a summary of the mode indicators that appear on the MC-83

display…

Indicator Meaning

% RH Indicates that the top reading is % Relative Humidity.

OCIndicates that the bottom reading is Temperature in OC.

OFIndicates that the bottom reading is Temperature in OF.

D.H Indicates that the MC-83 is in Data Hold mode (see

section 3).

REC Indicates that the Record Data mode is currently active.

(see section 4).

Max Indicates that the MC-83 is displaying the Maximum

recorded readings.

Min Indicates that the MC-83 is displaying the Minimum

recorded readings.

AVG Indicates that the MC-83 is displaying the Average

recorded readings.

LBT Indicates that the battery requires replacement.

Page 10

7. Humidity Calibration

The MC-83 is supplied pre-calibrated. Re-calibration will be required

periodically (approx annually), depending on application, environment etc.

75% and 12% Relative humidity standards are available from TPS. Table

1 shows the Relative Humidity characteristics of these two standards.

When making up your own standards…

•The solution must be saturated with the salt, i.e. no further solids will

dissolve.

•Use distilled water.

•Use a plastic bottle that allows the sensor tip to fit snugly into the top of

the bottle, making a good seal.

•Allow 24 hours after mixing for the temperature to stabilise.

•Standards can be stored (sealed) for approximately one year.
