QUICK REFERENCE

ON/OFF button turns unit on and off.

HOLD/SCROLL button alternates between the Auto Scroll mode and the Hold mode.

When the unit is initially turned on it will be in the Auto Scroll mode. It displays a reading,

pauses, then scrolls to the next measurement. Press HOLD button to stop the scrolling

and the display will read only the present measurement.

DISPLAY/MEM/ALM button switches between viewing current readings, high/low

memory recordings, and high/low alarm set points for relative humidity (RH),

temperature (°F, °C), and dew point (DP °F, DP °C).

CLEAR MEM/ALM OFF/SET button permits clearing the memory settings, turning off a

sounding alarm, and setting an alarm.

RH, TEMPERATURE, AND DEW POINT MEASUREMENT

1. Turn unit on by pressing the ON/OFF button.

2. Unit automatically begins scrolling through measurements for relative humidity,

temperature, and dew point. Indicators ( RH; °F, °C; DP °F, DP °C) appear on the

display to denote the current measurement.

3. Freeze the display at the desired measurement by pressing the HOLD button.

Display “freezes” at the desired measurement while the unit continues sampling.

4. Place probe near the substance to be measured and read display.

5. Return to Auto Scroll mode by pressing the SCROLL button.

6. Press ON/OFF button to turn unit off. This resets all stored memories and alarms.

MEMORY RECALL OPERATION

Unit’s memory function permits viewing the highest and lowest readings stored in

memory for relative humidity, temperature, and dew point. “HI” appears on the display

indicating highest reading stored, and “LO” appears on the display indicating lowest

reading stored. All measurements (relative humidity, temperature, and dew point) are

constantly scanned. If a new high or low reading is achieved while in the Display,

Memory, or Alarm modes, the reading is automatically captured and is available for

display.

Displaying highest/lowest memory readings

1. Press MEM button until the word “MEM” appears in the lower, right-hand corner of

the display. Unit is now in Memory mode.

2. If the unit is in Auto Scroll mode when the Memory mode is activated, the display will

scroll through the highest and lowest readings recorded for relative humidity (RH),

temperature (°F, °C), and dew point (DP °F, DP °C).

3. If the unit is in Hold mode when the Memory mode is activated, the highest reading

recorded for that specific measurement will be displayed. Press the SCROLL button

to return to the Auto Scroll mode and then press the HOLD button at any time to

“freeze” the display at a particular measurement.

Clearing memory readings

1. Verify the unit is in Memory mode by checking to see if the word “MEM” appears on

the display. If the unit is not in Memory mode, press the MEM button until “MEM”

appears on the display.

Note: Memories may only be cleared while the unit is in Memory mode and “MEM”

appears on the display.

2. While the unit is in Memory mode, press the CLEAR MEM button to reset all of the

memory settings. Memory settings will automatically reset to the current readings for

relative humidity, temperature, and dew point.

3. Exit the Memory mode and return to normal Display mode by pressing the MEM

button twice.

ALARM OPERATION

High and low alarm set points may be entered in any 0.1 increment for relative humidity,

temperature, and dew point measurements. When an alarm set point is tripped, an

audible alarm sounds constantly for 1 minute, unless turned off manually, and then

sounds once every minute to conserve battery life. After the first minute, a visual alarm

appears on the display as a flashing “ALM”. The alarm will sound if an out-of-range

condition exists irrespective of the measurement being displayed.

Setting an alarm

1. Press the ALM button until “ALM” appears on the display to indicate the unit is in

Alarm mode.

2. If the unit is in Auto Scroll mode when the Alarm mode is activated, the display will

scroll through the high (“HI”) and low (“LO”) alarm settings for relative humidity,

temperature, and dew point.

3. If the unit is in Hold mode when the Alarm mode is activated, the high alarm setting

for that specific measurement will be displayed. Press the SCROLL button to return

to the Auto Scroll mode and then press the HOLD button at any time to “freeze” the

display at a particular alarm setting.

4. Once the desired unit of measurement appears on the display, press the HOLD

button to “freeze” the display if necessary.

5. Press the SET button to advance the display in increments of 0.1. For rapid

advancement, press and hold the SET button.

6. Once the desired alarm set point has been entered, exit the Alarm mode by pressing

the ALM button and return to normal Display mode. Alarm is now activated and will

sound if an out-of-range condition occurs.

Note: When setting an alarm in degrees Celsius, the units advance unevenly because

the units are being advanced internally in the Celsius equivalent of 0.1° Fahrenheit.

Alarm set points may be entered in °F or °C but they must be equivalent.

Note: Very rapid changes in humidity and temperature may cause the dew point alarm

to sound a false alarm. A “phantom” sensed out-of-range dew point alarm may be

triggered by either the humidity sensor or temperature sensor sensing a change faster

than the other. (Example: instantly taking the probe from a 70°F, 80% RH environment

to a 20°F, 5% RH environment may trigger a false alarm.) This may be eliminated by

lowering the alarm set point for dew point or by turning the unit off and, after the probe

reaches an equilibrium, turning it back on.

Silencing an active alarm

Once an alarm set point is triggered, the alarm will continue to sound and flash until

turned off (even if the measurement value returns to an in-range condition). Silence an

active alarm by pressing the ALM OFF button in any measurement or any mode. The

alarm will NOT trip again until the current value passes through the alarm set point and

again is within a normal (non-alarm) range.

Example: If the RH “HI” alarm is set at 80.10 and the current reading is 80.20, the

alarm will sound. After the ALM OFF button is pressed, the alarm will be silenced and

will not be triggered again until the RH falls below 80.10 (resetting the alarm) and

then rises above the set point to 80.20 (triggering the alarm).

To determine which setting caused an out-of-range alarm, display the memory’s high

and low values and search for a value that is beyond the alarm set point.
