Troubleshooting and Servicing the Chart Recorder 7 .1 .7 Testing the probe circuit If you notice the LED is slowly flashing green, or temperature markings are slowly and repeatedly deviating from the calibrated temperature, then there may be a problem with the probe circuit. You may test the probe circuit to determine where the problem lies. When the chart recorder is put into probe simulation mode, a jumper is added to the probe circuit in place of the chart recorder probe. The jumper causes the circuit board to provide a fixed resistance that simulates a temperature reading. The stylus should move to a fixed temperature on the paper. - Page 27 Troubleshooting and Servicing the Chart Recorder 7 .2 .1 Cover and main power parts (standalone units only) Standalone chart recorder with various parts shown Label Description Replacement part numbers Label on schematic Probe 400799-1 Power connector with fuse Fuses are not included holder 115 V models: 120152 230 V models: 120379...
