Troubleshooting

General Fault Isolation

Power-Up Self-Test

See the MAC™ 800 Operator’s Manual, Chapter 2, “Equipment Overview: Getting Started” to verify operation.

On power-up, the system automatically runs an internal self-test. If all circuit tests pass, you will see the start-up screen.

Poor Quality ECGs

The next screen that appears after the start-up screen depends on the Power Up mode selected in System Configuration. The Resting ECG mode is the default Power Up mode.

If the equipment is not working properly, ask the following questions.

 Is the unit turned on?

 Have there been any changes in the use, location, or environment of

the equipment that could cause the failure?

 Has the equipment hardware or software been modified since last

use?

 Is operator error the cause of the problem?

Try to repeat the scenario exactly and compare that to the proper operation of the equipment described in the manual.

 Is the battery installed?

 When connected to the AC wall outlet, does the green AC power light

glow?

Poor quality ECGs can be caused by factors in the environment, inadequate patient preparation, hardware failures related to the acquisition module, lead wires, cables, or problems in the unit.

Battery Capacity

MAC Address

Troubleshooting

Q: What is the capacity of the battery?

A: We recommend that the MAC 800 be connected to AC power through a wall outlet whenever it is not in use. However, if operating the device without AC power, be aware that a fully-charged battery is capable of printing approximately 1000 single page reports or 2 hours of continuous operation (without printing).

Q: I need to provide the MAC address of the device to the network administrator to enable the LAN communication option. How do I obtain the MAC address?

A: Follow these steps to obtain the MAC address:

1. Open the Diagnostic Tests window as described in “Accessing the

System Diagnostics Function” on page 3-6.

2. Move the focus to the Service Report button and press the Enter key to select.

Calibration

3. Find the MAC address on the printed service report.

Q: How do I calibrate the MAC 800 system?

A: When it becomes necessary, you can calibrate the MAC 800 system using the following method:

1. Using a standardizing waveform generator, produce a 1.00 ± 0.01

-mV pulse signal with a rise-time no greater than 5ms and a width no greater than 100ms.

2. Connect the pulse signal to all available channels and set the gain to 10 mm/mV.

3. Verify the display pulses have an amplitude within ± 5% of the amplitude obtained when the 1.00 ± 0.01 -mV signal is applied.

4. Repeat the test for all fixed gain settings to verify the standardization pulse correctly reflects the gain setting.

NOTE

The error must be less than ±5% of the expected value or 0.5mm, whichever is greater.

5. Verify that the standardization signal appears on all channels.
