Monitor Mode

The instrument can be placed in Monitor mode by pressing and holding the Mode

switch for two seconds after a predictive (normal) temperature has been taken. This

mode will be indicated on the display by a capital M in the bottom right corner. Monitor

mode provides a direct readout of the probe temperature.

This mode of operation has the ability to provide long term monitoring of a patient’s

temperature. Unlike Predictive mode, Monitor mode will follow a temperature as it

rises or falls.

The typical slow rise in temperature when Monitor mode is used is due mainly to the

mouth temperature slowly recovering from placement of the colder (room

temperature) probe. The probe itself is actually very fast at rising to the temperature

of its surroundings, usually within a few seconds. Because of this slow mouth

recovery, the recommended time to wait before recording a Monitor mode oral

temperature is 3 minutes. Similarly, the recommended waiting period for an axillary

temperature taken in Monitor mode is 5 minutes.

Monitor mode is also useful in testing the accuracy of the combined probe/instrument

system when the probe can be warmed to a known temperature, as with a Welch Allyn

Model 9600 Calibration Tester or in a circulating water bath.

Note:

The instrument will shut off automatically if the probe temperature remains

below 28.9

C (84.0

F) or above 42.2

C (108.0

F) for more than 5 minutes.

If Monitor mode does not display expected temperatures or exhibits other problems,

refer to the

Troubleshooting

section.

Pulse Timer Mode (Model 678 only)

Pulse Timer mode is activated from a Low Power or Recall mode by pressing the

Timer button. Whenever the unit enters the Pulse Timer mode, it will emit an audio

beep at 0, 15, 30, 45 and 60 seconds. The display will then count up one second at a

time, “01”, “02”, ..., “60”.

Pulse timer mode will be terminated automatically upon completion of a 60 second

count and go back to low-power mode. The pulse timer can be shut off at anytime

during the 0-60 count by pressing the Timer button, the Mode button or removing the

probe from the probe holder. Connecting a probe will also terminate the pulse timer.

If the timer does not work or exhibits other problems, refer to

Timer Problems

in the

Troubleshooting

section.

Backlight (Model 678 only)

The backlight is turned on automatically in any mode except Low Power. Once the

backlight is turned on, it will automatically shut off whenever the instrument goes into

Low Power mode.

The backlight provides a display light for use in dark rooms. The LCD is backlit such

that all readings are clearly readable in a darkened room from a distance of 18 inches.

If the backlight does not work or is showing other problems refer to the

Backlight

Problems

section in the

Troubleshooting

section.
