Model OM-VLT is a programmable temperature data logger, strip
recorder and alarm device with integral digital display. The easy to
follow menu driven programming is done via the front panel keys.
The unit records, saves and prints up to 290 temperature readings at
predefined intervals. The OM-VLT produces an alarm when the
temperature goes out of the defined range or after the
temperature remains out of range for a certain period of time. The
OM-VLT prints temperature data directly via the integral printer and
can also send temperature data to an external PC. Communications
with a PC is done by using Windows Hyperterminal software
so no additional software is required. The OM-VLT can also
send alarms to an external device via the built-in relay contact.
Specifications
Temperature Sensor: Solid state IC, 10 m (33') long sensor probe
wire, 0.2" diameter
Temperature Measurement Range: -40 to 130°C
(-40 to 266 °F)
Temperature Measurement Accuracy: ±1°C (±1.8°F)
Temperature Writing and Storage Resolution:
0.1°C (0.2 °F)
Sample Rate: Programmable between 1 and 90 minutes in 1
minute intervals
Memory: Data logger saves the last 290 measurements; logging
starts as soon as the unit is turned on
Computer Interface: RS-232: 9600 baud, 8 data bits, parity none, 1
stop bit, flow control none
LEDs: Power, low battery, out of
paper, sensor, min, max
Alarms: High and low temperature, end of paper, no sensor; audible
(internal buzzer)/visual (alarm LED)/normally open relay contact
Audible Alarm (Internal Buzzer): Some alarms trigger the internal
alarm buzzer. The buzzer can be silenced by pressing EXIT on the
front of the data logger or by connecting the optional remote
buzzer silencer switch (OM-VLTSK) which momentarily shorts the
buzzer silencer contacts on the data logger. The alarm buzzer can also
be enabled or disabled via the data logger front panel menu
programming.
Temperature Alarm Operation: If the measured temperature goes outside the maximum
or minimum temperature limits for an amount of time equal to the defined alarm delay period (if any), an alarm is
sent – the internal buzzer sounds (if enabled), an alarm is sent to an
external device via the alarm relay contact (if enabled) and the alarm
LED lights.
Disconnected Temperature Sensor Alarm Operation: If the
temperature sensor is disconnected the display shows the message
nOS, the alarm LED lights and the internal buzzer sounds (if enabled).
End of Paper Alarm Operation: If the printer paper runs out,
the internal buzzer sounds
(if enabled), an alarm is sent to an
external device via the alarm relay contact (if enabled)
and the
out of paper LED lights.
Alarm Relay: 1 A, 12 Vac/Vdc
Alarm Delay Range: User selectable; No delay, 10 min, 30
min, 1 hr, 2 hrs
Printing Modes: There are three printing modes; full text
report (small font), time and temperature (large font),
graph format

Power: 12 Vac/Vdc via included 115 Vac 50/60 Hz adaptor
Battery Backup: 9 V alkaline
for up to 60 hours operation
Clock Battery: CR2032 coin cell, used for saving logged data and
configuration settings and for running the real-time clock
