Getting Started (continued)

select the mode (“Mode” in right display) from “All” to output all scan data, “ALAr” to output only alarm data, or “trAnS” to output data scanned only when the Hydra goes into or out of alarm.

Once the destination and mode have been set, enable Memory Storage by pressing: print. The “PRN” annunciator lights to indicate that Memory Storage is enabled.

Warning

No data will be saved unless the “PRN” annunciator is lit on the on the Hydra from panel florescent display.

Memory contents can be sent to the RS-232 port for listing directly to a printer (refer to Table 3-16 in Chapter 3) or through the computer interface.

Taking Measurements

Before taking any measurements, you might want to set up a few more channels... set up three additional channels, as described below. (Remember, use Gor Dwhen in inactive Mode to select a channel, and then press F.)

Channel

Function

0

V AC, 300V range

1

V DC, 30V range

2

(leave set up as "OFF")

3

Resistance, 3 mΩ range

4

Thermocouple Temperature ("°C" or "°F")

5 .. 20

(leave set up as "OFF")

Warning

Inputs may be connected to live voltages. To avoid electric shock remove inputs from live voltages before opening this module.

You need to connect wires to these channels before taking measurements. Insert a pair of test leads into the jacks on the front panel for channel 0. For channels on the rear Input Module, proceed as follows:

1.Remove the input module from the rear panel.

2.Loosen the two large screws on top and open the module.

3.Connect wires to the pairs of terminals for channels 1 and 3. We’ve enclosed some thermocouple wire for you to connect to channel 4; the thermocouple’s red lead must be connected to the "low" input terminal, labeled "L". (Note that the enclosed thermocouple is for demonstration purposes only. Measurements taken with it may be off by 1 - 2 degrees.) Refer to Table 3-14 in Chapter 3 to identify the type of thermocouple by positive lead color. This table also shows the appropriate usable temperature range.

4.Thread the wires through the strain-relief pins and out the back of the module.

5.Close the cover, secure the screws, and insert the module back in the instrument.

The instrument is now ready to take measurements. Start with the Monitor function, which takes repeated measurements on a channel.

Press G, Dto select a channel to Monitor.

Press Mto activate the monitor function.
