3B. Rear: The JEL-2400 has a stand at the back which is opened by grasping at the two finger slots and gently lifting the stand up. The stand has small posts that slide along the housing to open and close. - Page 4 Contains the sensor mount, a 15-Pin D-Sub connector and posts for securing the sensor to the device. The JEL-2400 is backwards compatible with all “D” style sensors with the exception of PMT's and SHD Low light level sensors. To connect the sensor, align the sensor’s male 15 pin connector to the meter’s female connector and apply slight...
- Page 5 Place the un-covered sensor in the test location. Cover the test light source, or turn it off. Press Zero. The JEL-2400 will take a measurement and subtract that value from all future readings until zero is pressed again.
- Page 6 Note: If light level is selected prior to selecting a calibration/sensitivity factor, an error message Set Factor will appear in place of light level readings (see 15Q for selecting factors). If OD and % Trans, are selected and no baseline 100% value has been set and error Set 100% will appear see 3G8 below to learn more about setting 100%) 3G3.

Page 7: Internal Battery Pack
Charging the battery is done through the USB 3.0 mini or micro port. WARNING: The battery pack in the JEL-2400 is expected to last for many years (up to 500 charge cycles). Batteries should only be charged, stored and used in temperature between 0 Deg C to 45 Deg C, or expansion and damage can occur. -

JEL-2400 so no damage will occur to the meter during saturation. 8C. Dynamic / Measurement Range: The JEL-2400 can measure current from 1 pA to 1 mA however the recommended range for calibrated readings is 50 pA to 1 mA. This range does not take into account the range of current the sensor is capable of supplying to the meter. -

10. Reverse Bias: The JEL-2400 can supply -5V or -9V to the detector through the D sub connector. The 5V bias can be used on silicon sensors to increase the response time. Bias voltage is required to supply the necessary voltage to sensors containing Photomultipliers, and Vacuum Phototubes. -
Page 11: Display Content
Cloak: Cloak provides a black and white low intensity display setting to minimize light output into the environment. This was designed to prevent light from the JEL-2400 display being included in the light level measurement. Cloak has a very large data capture button to allow the user to easily capture and store a single reading in the dark. -

(temperature, noise, ambient lighting). 14C. Integrate: Is used to measure dosage or exposure. When toggled on, the JEL-2400 will take the present reading and add it to the previous value, once per second, creating a sum of light measurements over time. When in integrate mode the units of the readings change to include *seconds. -

Use Smart Detector Factor must be enabled, in 15B3. 15B3. USE Smart Detector Factor: ON/OFF ON enables use of the sensor’s cal factors. Off only allows customer to use factors saved in the JEL-2400 meter. Page 13... - Page 14 Datalight III Meter or Flash. 15D. Auto Gain Range: On or off. The JEL-2400 has 3 relays that it cycles through when auto ranging from the lowest signals in the Pico amp range to the higher signals in the micro amp to 1 milli- amp range.
- Page 15 15G. 5V Bias On or Off: The default setting is off as there are numerous sensors that can be damaged or read incorrectly if bias is applied. When turned on, the meter will supply reverse bias to any sensor plugged into the device (see section 5 for pin out information pertaining to bias) Silicon sensors such as the JSED033, JSED100, JSPD025Y, and the JXRL series can be biased when measuring flashing or rapidly changing values to increase response time.
- Page 16 Select from Scientific notation on i.e. 1.06e-3 W/cm2 to Scientific notation off i.e. .001 W/cm2 (2e+2 lux becomes 200 lux) Note: the Display on the JEL-2400 allows up to 3 digits after the decimal place. When using scientific notation on, the device can display readings as low as e-13 with two decimal places, ie 6.23e-13.

2. Turn the Meter on, allow initialization to complete and verify the battery life is above 20% (no USB devices should be plug in during initialization) 3. Insert the USB stick into the USB A port on the side of the JEL-2400. 4. Click on Settings, and Scroll to the bottom of setting window. -
Page 21: Care And Handling
22. Care and Handling: The JEL-2400 internal board is a sensitive electronic device. Due to risk of board damage, only trained personnel should attempt opening the housing on the JEL-2400. Opening the JEL-2400 voids all warranties and may adversely affect the calibration of the meter. -
