Page 19: Operation
CHAPTER 4 OPERATION LED Control Operation and Status Function The ON/OFF state of the instrument can be determined by pressing the PRESS button for less than 0.5 seconds. If the instrument is ON, the status of the instrument will be shown by the LEDs. If the instrument is OFF no indication will be given (the LEDs will not blink). The instrument is turned ON by pressing the PRESS button until all LEDs light. At this point, the button can be released and the instrument will remain in the ON state. If the button is released before all the LEDs light (in unison), the instrument will remain in the OFF state. When holding the PRESS button while the instrument is ON, each LED will light in sequence. Continuing to hold the PRESS button until the last LED lights, turns the instrument OFF. At this point, releasing the button will result in no action being taken. This provides a mechanism to cancel (or ignore) the button press. Control of the instrument is performed by pressing and holding the PRESS button (while the instrument is ON) until the control LED corresponding to the desired operation lights. Releasing the button when the desired control LED is illuminated results in the corresponding operation being performed. - Page 20 The Control and Status Operation of each LED is as follows: GREEN LED: CONTROL STARTS A RECORDING Logger is turned OFF or in Low Power Standby state* STATUS Single-blink Logger is in Standby Mode (and not recording) Double-blink Logger is in Record Mode ORANGE LED: CONTROL STOPS A RECORDING Logger is not in an Overload condition STATUS Single-blink...

• SLEEP mode: The instrument enters the low power state if the button is not pressed for one minute. It will remain in this state until either the button is pressed or the internal clock reaches the start time for a scheduled recording. • RECORD mode: The instrument enters the low power state between sample sets. The slower the storage rate, the greater the portion of time the instrument is in the low power state. Thus, the slower the storage rate, the longer the instrument can record. • OFF mode: The instrument enters the low power state and will turn on at the time a recording is scheduled. Connecting the Simple Logger II to a Computer ®... -
Page 22: Recording Data
The instrument contains protection circuitry to prevent it from being turned on when the battery voltage is below 1.7V. There are two thresholds for the battery voltage: • The first is used to indicate low battery. The low battery indicator will blink when the battery voltage drops below 1.8V. • The second is used to determine when to terminate recording and turn the unit off. The shutdown threshold is when the battery voltage drops below 1.7V. Recording Data NOTE: The Simple Logger II is factory configured and may be altered ® to fit the users needs (see the Configuring the Simple Logger II section ®... -
Page 23: Stopping A Recording Session
4.4.2 Stopping a Recording Session 1. Press and hold the PRESS button. When the STOP (ORANGE) LED lights up, release the button. 2. The GREEN LED will change from a double-blink to a single-blink, indicating STANDBY mode. The data will be retained, even if the instrument is turned OFF. The recorded data is stored in Flash memory (maintained even in the absence of batteries). The recorded data may be downloaded to a computer. Downloading Recorded Data Recorded measurements stored in the instrument are transferred to a computer via the download command in the SLII Control Panel. For instructions on downloading data, see the Downloading Recorded Instru-... -
Page 24: Erasing Data From Memory
Erasing Data from Memory Erasing data from the instrument’s memory can only be performed while in the STANDBY mode. There are two ways to erase the memory: Erasing the Memory using the PRESS Button: 1. Press and hold the PRESS button. When the ERASE (RED) LED lights up, release the button. This will arm the instrument for an erase operation (when not in record mode). While armed to erase memory, the RED LED will blink at a fast rate for a period of five seconds. 2. Press the PRESS button for another 0.5 seconds to complete the erase operation. -
Page 25: Trend Measurements
direct measurement, the result of complex mathematical operations on a single or multiple input, or other channels. Sample Rate: The rate at which the instrument measures inputs. Storage Rate: The rate at which channel measurements are stored. 4.8.1 Trend Measurements The logger stores the TRMS calculation of each of the inputs. In addition, the user can define the storage rate, recording period and measurement format using the Configure Instrument dialog box in the SLII Control Panel software. Trend measurements are stored at this fixed storage rate. Normal Operation When the instrument is turned ON, the following occurs (provided there is sufficient battery voltage and no data is stored in the instrument’s memory): • The GREEN LED single-blinks. (STANDBY mode is active and the logger is not recording). •... - Page 26 Event: Recording with a Partial or Full Memory If the RED LED is double-blinking, the memory must be erased before any further recording can be performed. If the RED LED is single-blinking prior to starting a New Recording Ses- sion, the memory is partially full. To save, clear or check memory availability, use the Simple Logger ® Control Panel software. There may be instances where the GREEN LED is also double-blinking indicating that the logger is still recording. The user can choose to stop the Recording Session and download the session and/or erase the memory. NOTE: The logger memory cannot be erased while in the Record mode. The recording must be stopped first.

Page 27: 4.10 Reset Switch Operation
voltage may rise slightly after the unit turns itself off. In this event, the unit may turn on momentarily as a result of a button press. The batteries must be replaced before the recorded session(s) can be downloaded from the instrument. NOTE: Replacing the batteries while the unit is OFF will not result in the loss of data memory. The internal backup capacitor will maintain the clock and memory while the main batteries are being replaced. - Page 28 NOTE: It is recommended to only press the RESET switch when the logger stops responding to a normal press button control when not connected to DataView . It is not recommended to reset the instrument when the logger is ® recording, downloading or being configured.

CHAPTER 5 MAINTENANCE Use only factory specified replacement parts. AEMC will not be held ® responsible for any accident, incident, or malfunction following a repair done other than by its service center or by an approved repair center. Changing the Batteries WARNING: Turn the unit off before changing the batteries or loss of recorded data may occur. -
Page 30: Appendix A: Troubleshooting
APPENDIX A TROUBLESHOOTING Symptom: After being in a damp, cold environment, the logger does not function. Cause, Correction: Condensation may have formed inside the logger, shorting out the circuitry and discharging the battery. Allow the circuit board to dry thoroughly in a warm location. Symptom: Simple Logger II does not start recording. ® Cause, Correction: Make sure battery power is present. Make sure the PRESS button is pushed long enough to light the GREEN LED and released before the next LED lights. Make sure the RED LED is not double- blinking. If it is, memory is full and you need to erase the data (see § 4.7). -
