+ | This is transportable small EKG monitor originally used in ambulance cars. | ||
+ | |||
+ | === Field operation manual === | ||
+ | |||
+ | - Prerun check: | ||
+ | * Batteries: Displayed current should be more than 120 uA. If not, charge before use. | ||
+ | * Amplifier set to zero | ||
+ | * Open the display lid | ||
+ | - Connect EKG cable to U1 | ||
+ | - Connect EKG cable to subject: | ||
+ | * RED -> right hand | ||
+ | * YELLOW -> left hand | ||
+ | * BLACK -> right leg | ||
+ | * GREEN -> left leg | ||
+ | - Power ON: | ||
+ | * 1st time it will not start | ||
+ | * 2nd time it will boot up (wait few secs) | ||
+ | - Measuring: | ||
+ | * Select circuit (svod) | ||
+ | * Wait for signal to stabilize | ||
+ | - Press amplifier down to zero the signal | ||
+ | - If running away, press again | ||
+ | * Set speed | ||
+ | * Set brightness to usable minimum | ||
+ | - Power OFF: | ||
+ | * Disconnect subject | ||
+ | * Press power off | ||
+ | * Close the lid | ||
+ | |||
+ | <note warning> Do NOT touch contrast and vertical shift </ | ||

+ | |||
+ | === Recharging === | ||
+ | |||
+ | <note warning> | ||
+ | Recharge if displayed current is lower than 120 uA! | ||
+ | |||
+ | Do NOT use when recharging! | ||
+ | </ | ||
+ | |||
+ | - Screw out batteries (back panel) | ||
+ | - Pull out charger + connectors | ||
+ | - Charger LED: | ||
+ | * Blue = fully charged | ||
+ | * Red = charging | ||
+ | - Power source - any 5V (build in microUSB connector) | ||
+ | - Recharge BOTH batteries, ONE in a time | ||
+ | - Screw charge + connectors back | ||
+ | - Runtime ~6 hours | ||
+ | |||
+ | === PC === | ||
+ | |||
+ | - Set brightness to minimum | ||
+ | - Connect Arduino cable to C2 (SW same as [[project: | ||
+ | - BLACK wire is ground | ||
+ | - Set signal amplifier to reasonable minimum | ||
+ | |||
+ | Script for gnuplot to display all circuits (svody) in one plot. Let the circuits be: 1.txt for I, 2.txt for II,... 6.txt for aVF. | ||
