Monroe 244AK 靜電電壓表
• Measurement Without Physical
Contact
• Accuracy Better Than 0.1% at Almost
any Probe-to-Surface Spacing
• Full Complement of State-of-the-art
High Ferquency Probes
• Provision for Master/Slave Operation
Side- and end-viewing probes accommodate various mounting requirements. Specialty high-resolution probes allow the 244AK to resolve spot diameters as small as 1 mm. Probes include air purge capability to prevent ingress of particulate.
For typical input step: <3ms (10% to 90%)
for 1kV step: <2½ms (10% to 90%)
for 2kV step: <3½ms (10% to 90%)
for 3kV step: <4ms (10% to 90%)
Range:
±3000 volts, auto polarity.
Accuracy:*
0.1%, ±0.003%/°C over +20 to +40°C range (at recorder output). Useable to +50°C.
Speed of response:*
Settling time:
<3½ms to 1% of 1kV step input.
Frequency response:
Small signal frequency response typically ±3db to >300Hz.
Drift:*
<0.01V/hr after 1 hr warm-up (0.003V/hr typical). Not measurably affected by 10°C temperature variation or changes between 10% and 90% relative humidity.
Noise:*
<0.3V rms or 2 volts peak-to-peak wide band (bandwidth restricted to<1kHz) referred to input.
Surface resolution:
Determined by probe aperture size and surface-probe separation. Standard type 1017AE & AS probes with 0.07” (1.75mm) aperture will resolve a 0.10” (2.5mm) spot at 0.02” (0.5mm) separation.
Recorder output:
Compressed analog output is input divided by 1000 (optional Model 244AK has divide by 200) for external loads greater than 1KΩ. Output connector is BNC.
Output filter:
Bessel low pass filter with 0.7ms constant delay.
Size:
4 x 8½ x 14 inches (10 x 21.8 x 35.6 cm), 1.75” rack mounting available (1 or 2 per rack).
Weight:
7 lb. (3.2 kg)
Power requirement:
100, 115, 230 VAC, ±10%, 50/60Hz, 15 watts.
