A hand-held counter with bench top performance, the Model 5003 is a highly compact battery powered frequency counter which offers the convenience of a hand-held multimeter. Its performance exceeds that of many bench top counters of much higher cost.
A large and clear display:
Despite its compact dimensions, the Model 5003 incorporates an 8 digit liquid display crystal of the size you?d expect to find on a bench top instrument. A full range of indicators provide indication of measurement function, measurement time, overflow, trigger activity, low battery, and the measurement units. Operation is simple with all functions and ranges selected using just five large buttons.
Wide frequency range and high sensitivity:
The Model 5003 can measure frequencies in the range 5Hz to 1300 MHz. Unlike many counters, the sensitivity is high across the whole frequency range with no dead spots. A low pass filter can be selected to reduce high frequency signal noise and ensure stable readings at lower frequencies.
Low power consumption and push-to-measure:
Model 5003 has a remarkably low power consumption enabling it to operate for many hours from a standard 9V battery. Alternatively it can be operated using a AC adapter. A push-to-measure capability gives a virtually instantaneous reading followed by an automatic power down after 15 seconds. This provides greatly extended battery life where continuous monitoring of the signal is not required.
Reciprocal counting for improved resolution:
The Model 5003 uses a reciprocal frequency counting technique which involves multiple period measurements followed by computation of the reciprocal. The system, yields at least 7 digits of resolution per second of measurement time and can measure low frequencies to a resolution of 0.0001mHz
Frequency and period measurement:
The Model 5003 can display signals in tenths of period as an alternative to frequencies to 25MHz.
Hold Function:
A hold button allows readings to be frozen on the display for measuring non-continuous signals or recording results later.
