Product Information Facts Congratulations on your new Ergometer.
Operating Instruction Here are instructions for connections and opportunities for connection to external communication. The need for advanced technical documentation/protocols for systems building, contact Monark Exercise AB, Sweden. Power on crank or flywheel When the Ergometer 831 E is adapted to ECG-work tests, it is set to measure the power on the crank. When the Ergometer 831 E is adapted to fitness tests, it is set to measure the power on the flywheel.
RPM Display and Visual Metronome/Pulse Initial operation The metronome (the two green LED bars in the middle) flashes once per handle stroke at a preset rate. The two green LED bars in the middle can also be set to show pulse. It makes one flash for every heart beat. Crank handle frequency compared to metronome rate is always shown. Although all 831 E ergometers are 100 % calibrated at the factory, the user may wish to verify this by performing the mechanical calibration of the pendulum weight.
Connection to controller Setting of terminal Setting of commando type (PC or ECG Device) When using a terminal (Art. No: 9339-51) do as follows: From programme version R15 First check the brake belt tension. If the belt is too tight loosen it a little by moving the pendulum to about 4 kp and hold it there for a few seconds. Then the force-adjusting servo will loosen the belt tension. To be sure that pendulum positions are correct, do a calibration. See ”Electronic calibration”. 1.
Connection to PC To connect a PC to the ergometer, use a 0-modem cable (RS232) with a 9-pin D-sub female at each end. If no RS232 Serial port is available on the computer use a USB serial RS232 converter. Common commands: • • To control the ergometer use the PC software supplied with the ergometer or other PC software made for the Ergomedic 831 E. From software version MEC3V11R14 and later settings can be made from a PC in terminal mode if the terminal is not available. Set PC in terminal mode.
Connection to an external ECG device, digitally controlled 1. Connect the terminal to the main unit on the front of the bike (use the 0-modem cable with a 9-pin D-sub female at each end). 2. Connect the net adaptor to a suitable wall outlet and to the Monark Ergometer 831 E and then turn power on. 8. Return to main menu by pressing ’0’ and press ’0’ again to finish. The computer will then save the settings in the memory before it turns off. Computer will start up again automatically after a few seconds. 9.
Analogue control Printer The work load of the Ergometer can be controlled by external devices such as an analogue ECG device (must be between 2 and 4 volts to operate properly). For settings, see the manual for the terminal and manual for the software. The 831 E Ergometer interfaces to several optional devices. A parallel interfaced printer may be attached to provide written reports.
Calibration Daily check The 831 E is a mechanically weighted and braked ergometer, making performance validation a simple procedure. Calibration is necessary to match the mechanics of the ergometer to the electronics of the computer. The work performed on the ergometer is the product of the weight lifted times the numbers of revolutions (factored). Validation includes both mechanical and electronic procedures. For more information, see Manual terminal (art. No: 7950302) or the manual of the software.
Validation of force Electronic calibration From main menu go to any start display with Newtons (N). See Fig: Force. A daily check of the pendulum force sensor should be preformed. If the procedure reveals an error, recalibration may be necessary. The values are saved even if you turn off the power and if you physically move the bike.
Electronic calibration - terminal Electronic calibration - with the pendulum 1. Check at the bottom of the flywheel that the brake belt is loose, see Fig: Brake belt is loose. If not, move the pendulum to 4 kp and hold it there for some seconds. Move the pendulum down to 0-position again, and check that the brake belt is loose. 2. Adjust the meter panel, see section "Zero adjustment of meter panel", so that the index line of the pendulum is opposite the 0-index of the scale, see Fig: 0-position. 3.

Calibration Validation The 831 E is a mechanically weighted and braked ergometer, making performance validation a simple procedure. The work performed on the ergometer is the product of the weight lifted times the numbers of revolutions (factored). Validation includes both mechanical and electronic procedures. If the ergometer fails to pass any section of the validation, proceed to the calibration and/or service menu (‘99’ in the main menu).
Electronic calibration Calibration is necessary to match the mechanics of the ergometer to the electronics of the computer. The following steps are required to recalibrate the electronics to the pendulum scale. 1. Check at the bottom of the flywheel that the brake belt is loose. If not move the pendulum to 4 kp and hold it for a few seconds. Move the pendulum to the zero position again. Check that the brake belt is loose. 2. Align the force scale with zero marker on the pendulum.
Calibration of pendulum weight Although all Ergometers are calibrated at the factory the user may wish to verify this by performing a mechanical scale calibration. If so, please do the following. Remove the cover from the flywheel. Loosen the balancing spring from the brake belt. Check that the 0-index of the scale is in line with the index of the pendulum weight. Adjust if needed. Note: Wait until the flywheel is not moving any longer. Connect a known weight, e.g. 4 kg (Art.
Testing with Ergomedic 831 E The versatility of the 831 E Ergometer enables it to be utilized in a variety of testing environments. The precision and reproducibility of measurements made with the ergometer in conjunction with the ease of testing, allow it to be employed in clinical exercise stress facilities, corporate fitness programs and health clubs. The backgrounds of both the individuals being tested and those administering the test may be vastly different in these widely varying testing situations.
Heart rate (Telemetry system) Subject supervision The test subject’s heart rate can be monitored by chestbelt telemetry system. The system with chestbelt electrodes is standard equipment. The ergometer performs automated tests virtually by itself, requiring minimal intervention by the operator. This allows the operator to pay careful attention to the test subject without distraction.
Reviewing results The maximum oxygen uptake is the standard measurement of cardiopulmonary fitness. Dependent on the linear relationship between work and oxygen uptake and between work and heart rate, the heart rate response to work may be used to estimate the oxygen consumption. If the maximum heart rate is considered, the maximum oxygen consumption may be determined.
Operation interferences It is normally considered that about 70 % of all shutdowns on small computers are caused by mains interferences, i.e. at shot over voltage. These interferences can often be caused by different machinery, which is started or stopped. The processor in the computer is then reacting incorrectly or is not working at all. The problems can be solved by means of a mains interference protector, which is connected between the mains and the transformer.
Error messages Message Reason Test Aborted An automatic protocol operation has been stopped too early. No results are available. Where to obtain additional information The user may require more information concerning several areas of the ergometer usage. This manual was intended to instruct the reader primarily in the operation of the ergometer. References are made to related topics in the discussions concerning the testing procedures and the protocol operation sections.
Service Service check & maintenance Warning It is important to carry out a regular service on your ergometer, to ensure it is kept in good condition. Make sure the voltage indicated on the appliance corresponds to the local mains voltage before making connections. Warranty EU countries - Private use If you are a consumer living in the EU you will have a minimum level of protection against defects in accordance with EC Directive 1999/44/EC.
Batteries If the meter is battery-operated, the batteries are in a separate package at delivery. If the storing time has been long the battery power can be too low to make the computer act correctly. Batteries must be changed. Alt. 3: To loosen the belt on other bikes remove all possible tension. Observe how the belt is connected. Take it apart and remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.
Chain 1/2“ x 1/8“ It is strongly recommended to keep the chain clean. Dirt build-up on the chain will cause excess wear. A chain lubricant and solvent for normal road bikes may be used. Check the lubrication and tension of the chain at regular intervals. In the middle of its free length the chain should have a minimum play(3) of 10 mm (1/4 inch). See fig: Chain adjustments.
Freewheel sprocket When replacing the freewheel sprocket remove frame covers if necessary. Dismantle the chain as described in part ”Chain 1/2” x 1/8” ”. Loosen the axle nuts and lift off the flywheel. Remove the axle nut, washer, chain adjuster and spacer on the freewheel side. Place the special remover (Art. No: 9100-14) in the adaptor and place the spacer and axle nut outside. See fig: Special remover. Replace sprocketadaptor and assemble the new parts in reverse order according to the above.
